In most of the cases, canal network in Greater Colombo region work as the drainage system of the urban area and as the backyard of the city. Therefore, there is a lack of attention to the canal waterfronts by the government and by the public. Hence, this research was to find out and evaluate the factors, which will affect the quality of life of people along urban canal waterfronts. It has been discussed in terms of liveability through a series of carefully selected indicators. Liveability surveys were conducted along five canal waterfronts and the participants’ perceptions were taken. Every canal waterfront was assigned a rating of over 25 qualitative and quantitative factors (set of indicators) across six broad categories (dimensions): safety, comfort, health and wellbeing, mobility, environment, and socio-cultural factors. Each qualitative factor was given a rating from 1(tolerable)-5(intolerable). Qualitative factors were then combined with quantitative factors through a series of equations to form the liveability index. According to the proposed liveability index, transport dimension index is ideal (100), while the health and well-being dimension is the lowest (27). This will help for the creation of government policies, plans, rules and regulations and when implementing projects along urban canal waterfronts.

Taking China’s national intangible cultural heritage (ICH) Zhuang brocade as the research object, its cultural traits were extracted through scientific methods from the perspective of Kansei Engineering. Samples were collected through desk research, expert interviews, and questionnaires for qualitative and quantitative research. The semantic differential method was adopted to analyze the vocabulary descriptions of different types of Zhuang brocade samples, and the Likert scale was used to measure the viewer’s visual perception. Eye tracker experiments were conducted to verify and further explore the cultural traits of Zhuang brocade so that the emotions in this ICH can be quantified more scientifically. Based on the heat map and data, scientific and reasonable descriptions and typical shapes best matching Zhuang brocade cultural traits were acquired. By using new technologies to interpret ICHs, this study proposed another way to extract cultural traits from ICH. The extracted Zhuang brocade cultural traits in this study could help improve the understanding of Zhuang brocade. This study could also provide certain references for the modern application and design of Zhuang brocade.

The effective utilization of a communication channel like calling a person involves two steps. The first step is storing the contact information of another user, and the second step is finding contact information to initiate a voice or text communication. However, the current smartphone interfaces for contact management are mainly textual; which leaves many emergent users at a severe disadvantage in using this most basic functionality to the fullest. Previous studies indicated that less-educated users adopt various coping strategies to store and identify contacts. However, all of these studies investigated the contact management issues of these users from a qualitative angle. Although qualitative or subjective investigations are very useful, they generally need to be augmented by a quantitative investigation for a comprehensive problem understanding. This work presents an exploratory study to identify the usability issues and coping strategies in contact management by emergent users; by using a mixture of qualitative and quantitative approaches. We identified coping strategies of the Pakistani population and the effectiveness of these strategies through a semi-structured qualitative study of 15 participants and a usability study of 9 participants, respectively. We then obtained logged data of 30 emergent and 30 traditional users, including contact-books and dual-channel (call and text messages) logs to infer a more detailed understanding; and to analyse the differences in the composition of contact-books of both user groups. The analysis of the log data confirmed problems that affect the emergent users’ communication behaviour due to the various difficulties they face in storing and searching contacts. Our findings revealed serious usability issues in current communication interfaces over smartphones. The emergent users were found to have smaller contact-books and preferred voice communication due to reading/writing difficulties. They also reported taking help from others for contact saving and text reading. The alternative contact management strategies adopted by our participants include: memorizing whole number or last few digits to recall important contacts; adding special character sequence with contact numbers for better recall; writing a contact from scratch rather than searching it in the phone-book; voice search; and use of recent call logs to redial a contact. The identified coping strategies of emergent users could aid the developers and designers to come up with solutions according to emergent users’ mental models and needs.

The removal of textile reactive dye from an aqueous solution on a new adsorbent prepared from waste cotton knitted fabric was investigated in this study. Waste cotton textile, used for the production of adsorbents, is a by-product of the cutting of stacked parts of cotton knitwear planned for the production of women’s T-shirts. The degree of efficiency of a paper pattern determines the amount of collected waste. The qualitative and quantitative characterization of the new adsorbent showed carbon and oxygen to be dominant in the chemical composition. A longer contact time means a greater amount of dye on the adsorbent, i.e. the dye concentration in the solution decreases with the duration of the adsorption process. The percentage of removed dye decreases with an increase in the initial dye concentration in the solution. However, the actual amount of adsorbed dye increases as the initial dye concentration increases. The results for equilibrium adsorption show that the Langmuir isotherm can be used for the interpretation of reactive dye adsorption on a new adsorbent. The pseudo-first order model can be fully used to describe the kinetics of dye adsorption on an adsorbent, with respect to valid results for statistical indicators. Based on the results, it can be concluded that the new adsorbent obtained from waste textiles has the potential to remove textile reactive dye from aqueous solutions.

Abstract Background The Department of Health and Human Services and the Food and Drug Administration released the Safe Importation Action Plan in July 2020 detailing methods to import medicines from Canada to combat increasing drug costs. In November 2020, Florida became the first state in the United States to create and propose an importation plan from Canada. This study examines the proposal submitted by Florida, Florida pharmacists’ perceptions of the program on patient safety, and Florida pharmacists’ thoughts on the pharmacy operational impact. Methods This was a cross-sectional study utilizing an electronic questionnaire sent to pharmacist members of the Florida Pharmacy Association. The survey incorporated closed-ended and open-ended questions. The results from the study were reported and analyzed through descriptive statistics, qualitative and quantitative data. Results Two-hundred and forty-four pharmacists responded to the survey. Of those respondents, 25% stated they had no knowledge about Florida’s drug importation plan. Less than 12% of respondents stated they would trust the safety and quality of imported medicines. Seventy percent of pharmacists expressed concerns regarding the changes required in pharmacy operations to increase medicine safety. About half of the respondents questioned whether this plan would promote cost-savings as intended. Conclusion Florida pharmacists believe the drug importation plan does not address all aspects of patient and medicine safety and expressed concerns regarding logistical operations of a pharmacy. This article highlights those concerns and acts as a summons to action.

Initially founded in 1955 as a platform for Dutch photojournalists to increase international exposure, the World Press Photo competition has grown into the most prestigious contest of photojournalism worldwide, making it an important arena for journalism research. Using qualitative and quantitative content analyses, this study examines all photos shown in the competitions from 1960 to 2020 (N = 11,789) considering the origin of jury members (N = 686), participants (N = 132,800), placements (N = 2347) and the Human Development Index (HDI) of the countries. The topics displayed on the photos, their degree of negativity, and potential power structures in the photos are analysed over time both in terms of continental and HDI-related differences. Significant results show that Africa, Asia, and South America are more frequently depicted by the topic conflict and characterised by negative images than continents with industrialised nations (Australia/Oceania, Europe, North America). Participating European countries have a significantly higher average number of jury members, participants, and placements than participating countries from Africa, Asia, and South America, which seems to account for a dominant Eurocentric view. Implications and critical discussions are summarized in three interim conclusions at the end of this extended paper.

The possibilities and feasibility of using the Bayesian network of trust and logistic regression to predict the content of nitrate nitrogen in the 0-40 cm soil layer before sowing have been investigated. Data from long-term multifactor field experience at the Siberian Research Institute of Farming and Agricultural Chemization of SFSCA RAS for 2013-2018 were used to train the models. The experiment was established on leached chernozem in the central forest-steppe subzone in 1981 in the Novosibirsk region. Considering the characteristics of the statistical sample (observation and analysis data), the main predictors of the models affecting nitrate nitrogen content in soil were identified. The Bayesian trust network is constructed as an acyclic graph, in which the main (basic) nodes and their relationships are denoted. Network nodes are represented by qualitative and quantitative plot parameters (soil subtype, forecrop, tillage, weather conditions) with corresponding gradations (events). The network assigns a posteriori probability of events for the target node (nitrate-nitrogen content in the 0-40 cm soil layer) as a result of experts completing the conditional probability table, taking into account the analysis of empirical data. Two scenarios were analyzed to test the sustainability of the network and satisfactory results were obtained. The result of the logistic regression is the coefficients characterizing the closeness of the relationship between the dependent variable and the predictors. The coefficient of determination of the logistic regression is 0.7. This indicates that the quality of the model can be considered acceptable for forecasting. A comparative assessment of the predictive capabilities of the trained models is given. The overall proportion of correct predictions for the Bayesian confidence network is 84%, for logistic regression it is 87%.

This study centers on a retrospective investigation of effective and pedagogic planning of academic digital courses taught during the COVID-19 crisis, from the students’ perspective. We shall focus on the difference between the traditional, teaching-centered paradigm, and the modern learning-centered approach, while emphasizing the formulation of learning outcomes in online study expanses, in light of the learning experience imposed on teachers and students at the various academic institutions.The study explored the learning outcomes from students’ point of view, as well as the benefits and challenges embodied by formulating learning goals in the post-COVID era, according to the learning-centered paradigm, relating to the strengths and weaknesses of the Zoom teaching method from the students’ perspective, predicated on 1,828 students from several institutions. We used a mixed methods design incorporating qualitative and quantitative analysis to develop the Online Teaching Recommendations (SOTR) model. We used Structural Equation Modeling (SEM) for goodness-of-fit.The research findings indicate that the various types of e-learning challenge academic institutions to carry out renewed thinking about the main potential advantage of physical academic institutions where students and teachers meet, talk, and discuss directly and unmediated, compared to virtual bodies of knowledge and teaching that are evolving at present and that are allegedly threatening to render universities irrelevant.
