Site-Specific Traffic Loading Estimation Challenges in Structural Pavement Design Process in Qatar: A Case Study

Upon the design of any pavement structure, three fundamental external design parameters have to be considered throughout the design process: the characteristics of the subgrade, traffic loads, and environmental conditions. This paper focuses on the main challenges being faced to estimate site-specific traffic loading for a pavement design due to the lack of accurate and recent traffic data. A case study for a pavement structural design process for an actual expressway project in the State of Qatar is discussed in this paper. This case study goes through traffic loading calculations inputs; the Average Daily Traffic (ADT), Truck Factor (TF), as well as Heavy Good Vehicle Percentage (HGV%). The challenges of calculating these site-specific traffic loading inputs are discussed through investigation of the accuracy in traffic loading estimation using Qatar Strategic Transport Model (QSTM), and how the model can be incorporated in the design. Besides, limited available Wight-In-Motion (WIM) surveys have been discussed and the paper ends with the conclusion that rich availability of traffic data enhances the accuracy of the pavement structural design. It affects significantly the value engineering practice, and results in sustainable pavement sections

The Effect of Television and Electronic Advertisements on The Mental Image of Women Among A Group of Female Media Professionals

The study aimed to know the effect of television and electronic advertisements broadcast on Arab television screens and on websites on the mental image formed by a group of female media professionals affiliated with the Arab Media Center about women, by answering the sub-questions of the study, the study adopted the descriptive approach through the study tool, which is the questionnaire designed to answer the questions of the study through the respondents, that consisted of 200 female individuals who watch TV advertisements and follow them on the website, and after filling out the questionnaires, analyzing and interpreting them, the following conclusions were reached, the reasons for the respondent’s viewing of advertisements varied, but the largest percentage 94%, was that they watch advertisements involuntarily while watching TV or electronically presented material. This is what is classified as accidental exposure. The percentage of those who believe that the use of women in advertising greatly distorts the image of women is 66.5%. 91% of respondents agreed that women's rights associations and organizations must exert pressure to preserve the image of women and to educate society about their true role through various media, with a rate of 89.5%, the respondents expressed that they were shy when watching an advertisement that aroused in front of family members. 89% of the respondents believe that the ads that appear on social media and YouTube contain in their content greater freedom, and therefore the size of their distance from Arab values is greater, and in the same percentage came the emphasis on the need for some competent authorities to implement training courses for Arab ad directors to comply with our customs and traditions. The percentage of supporters decreased to 30% for the idea that advertising can only be successful by showing the charms of women, the woman's mind by presenting her as a consumer who does not care and only thinks about her elegance and beauty 30%. The study recommended that if a woman must appear in the advertisement, then this appearance should be appropriate to her reality and reflect the real role of women in society. Women's rights associations and organizations must exert pressure to preserve the image of women and educate society about their true role through the various media

Investigation of the Antimicrobial Preservatives in the Dairy Product (Labneh)

The aim of this study was to investigate the presence and levels of antimicrobial preservatives (natamycin, benzoic acid and sorbic acid) in the dairy product, Labneh. One hundred and fifty Labneh samples of 10 different trademarks were collected from the Jordanian markets in January, April and July 2013 to be analyzed. The obtained results indicated that 30% of the samples contained natamycin, 20% contained sorbic acid, 10% contained benzoic acid, and none of the detected preservatives were found in 40% of the samples. Results revealed that the highest level of antimicrobial preservatives detected in the Labneh samples was benzoic acid, which ranged from 5.70 to 365.4 mg/kg, while natamycin ranged from 11.74 to 76.98 mg/kg and sorbic acid ranged from 77.08 to 321.6 mg/kg. None of the samples contained more than one preservative. This study demonstrated preservative addition and amount was made with no consideration of seasonal variation. Results also showed that Labneh samples produced in facilities that apply HACCP systems met the required conditions without the addition of any preservatives.

Forms and functions of jokes disseminated during the Covid-19 pandemic in Jordan

People in Jordan have suffered the effects of the Covid-19 pandemic. The Jordanian government took some pre-emptive measures to curb the spread of the virus, including the announcement of indefinite curfew and nationwide strict lockdown. Humorous texts appear to be the people’s key to escape from life stress, minimise the pressure of unpleasant situations and increase pleasure. Jordanian humour attracts our attention to find out what it does during the Covid-19 pandemic and investigate its structure. To pursue this aim, a sample of 50 jokes and memes were collected from Facebook and WhatsApp in 2020 and analysed using the General Theory of Verbal Humour (GTVH). The researchers conducted a systematic and detailed analysis of the data relying on the six knowledge resources postulated by the GTVH, which are script opposition, logical mechanism, situation, target, narrative strategy and language. The analysis showed that humour can be viewed as a tool to release the tensions caused by Covid-19 restrictions on mobility and lockdown. It also revealed the people’s comments on different aspects of their life during the pandemic, including but not limited to social contact, economic status and education. In most of the analysed texts, humour is playful and serves the function of decommitment. This study offers insights into Arabic humour discourse, showing how jokes may serve the emerging context and encourage conducting studies on humorous texts in various settings to show what roles they would play

Self-Reflections in a Personal Space: Investigating the Process of Self-Portrait Painting by Academic Research

The purpose of this practice-based paper is to investigate the artistic reflections and self-aesthetics into the process of artwork making. Every stage of this process represents a particular significance from the initial stage to the finishing stage. Furthermore, this exploration aims to develop the employment of practical research in the field of Visual Arts on personal, communal and institutional levels. In this exploration, the methodology is the vehicle that transforms the research into reality. Making the artwork itself is the methodology, and this process is the primary reference of the present research. Therefore, the author presents the synthesis of the artwork making rather than the analysis of its aftermath, the focus in this context is the construction of the artwork. This is the result of this research, the artwork itself. Regarding the employability aspects of this approach, it involves the practitioners and researchers in the fields of the visual arts toward further realizations of the actual creative process. This employability takes place into the signs of progress on different levels through academic and artistic practices in schools, universities as well as higher learning and teaching institutions. The present practical paper is significant because it investigates reflections of the cultural identity as well as the narratives of personal memory into academic research. In the multicultural present temporality, research-oriented artists highlight the diversity of their societies and represent significantly personal aesthetics as themes in their artworks. This approach would elevate the mutual understanding among people from different aesthetical backgrounds; people's trends enhance multicultural perceptions, harmony, and coexistence. In addition, artists in this regard illustrate such an approach in their visual art when they compose practice and research with the symbolic content, which reflects social motives. Artists practice such art to critique the violent content in communication media and educate people that media may fake reality to create more audience and viewers. This study focused on the significance of subjective representations in contemporary arts, and the impact of such representations on the mutual understanding among people of multicultural societies.

People’s Reflections in the City: Exploring the Painting Practices of Figurative Expressionism by Academic Research

This paper is a practical outcome of a multidisciplinary research project conducted by the authors on the contemporary and modern practices of the Improvisation in Arts. All the authors are research-oriented practitioners in the fields of visual arts, performance arts, multimedia, Information and communication technologies as well as vocational training. Furthermore, the drawings, paintings, and sketches are all made by the correspondent author Assistant Professor Dr. Mohammed Baker Mohammed Al-Abbas as part of his research-oriented artistic practice through the hybrid painting techniques. Abstract The present studio-based paper aims to explore the creative reflections of the aesthetics of otherness within the practical phases of the painting production. This paper represents an experimental endeavor to create a two-dimensional artwork, which is a hybrid painting technique on canvas with mixed media and acrylic paints. Within such a specific practice-based context, each phase of this practical approach outlines a critical significance from the first phase of creating that painting to the completing phase. The practical methodology is the tool that converts the researcher's/artist's vision into creative academic production. The process of creating the painting on the canvas is the methodology; such manner turns to be a primary reference for the present exploration. There is a significant paradigm in this approach, which focuses on the artwork as a morphological creature being created by the researcher/artist rather than a consequent result that only exists as a finished/complete/polished outcome. The outcome of this research is the record of the artwork production itself. This record presents visual references of the artwork progress as well as a textual reflective narrative to describe this process with written words. This research-oriented artistic attempt introduces the artists and researchers in the domains of the Fine Arts to integrate the process of art-making into the methodologies of academic research. It is an academic text, reflective text as well as sequential images recording the artwork making. This studio-based experimentation is significant because it examines the aesthetics of the otherness into the expressive figurative abstraction in painting. Furthermore, the impact of such a studio-based approach manifests on advancing applications of the artistic oriented research in the field of Fine Arts globally on curatorial and academic levels.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
