{"title":"The Applicability of Design Thinking in the Tourism Sector, Kwazulu-Natal, South Africa","authors":"Zahir Sayed, Cecile N Gerwel Proches, Abdullah Kader, Simon Taylor","doi":"10.32388/arjmsr","DOIUrl":"https://doi.org/10.32388/arjmsr","url":null,"abstract":"One of the most significant corporate trends nowadays is design thinking, which gives firms the ability to develop their strategic thinking capabilities in order to tackle difficult problems. The goals of design thinking are to transform enterprises, encourage imaginative abilities, pinpoint needs and opportunities, and provide fresh ideas and scenarios for the company. South Africa's economy can grow as much as is desired by including all of these aspects. Design thinking is a capability that may deliberately assist the South African tourism industry in attaining its aspirational goals of increasing visitor arrivals, accelerating job development, and unleashing entrepreneurial prospects across sub-sectors that are closely related to the tourism sector. Tourism industry stakeholders must be aware of the evolving consumer demands. Understanding whether design thinking might be applied to the tourism sector in KwaZulu-Natal, South Africa, and whether doing so may be effective and advantageous for this sector, was the study's primary objective. Purposive sampling was used in this study's qualitative research approach. Eleven members of the tourism industry participated in a design thinking workshop, a focus group, and interviews in August and September 2021. The main conclusions showed that design thinking would be an effective technique to support improvements and innovation in the tourism sector, as all participants confirmed and agreed. The study's findings have led to various factors that can help design thinking improve tourism industry business. It is recommended that though design thinking can boost business in the tourism industry, a number of contributing factors must be properly implemented.\u0000","PeriodicalId":503632,"journal":{"name":"Qeios","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141118107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Impact of integrating smartphones in the teaching and learning of Mathematics in Mberengwa district, Zimbabwe","authors":"Kudzaishe Ganyani, Stella Muchemwa","doi":"10.32388/gts31s","DOIUrl":"https://doi.org/10.32388/gts31s","url":null,"abstract":"Worldwide, the utility of smartphones in the teaching and learning of Mathematics has been greatly recognized and taken advantage of. This is mainly because of the precisions this technology can bring in the classroom. This study investigated the impact of integrating smart phones in the teaching and learning of Mathematics at secondary schools in Chegato Cluster in Mberengwa district, Zimbabwe. It also examined strategies that can be used to enhance the use of smartphones in these schools. The study used a mixed method approach where both qualitative and quantitative data was gathered and was used to answer the formulated research questions. Ten parents, 10 Mathematics teachers, 4 school heads and 40 learners participated in the study. The study found that the introduction of the competence-based curriculum by the ministry of Education in Zimbabwe, which is in solidarity with Education 5.0 calls for the use of smart phones in the teaching and learning of Mathematics which ensures that several modern skills are being acquired by learners in Chegato secondary schools. Learners in Chegato Cluster benefit by using smartphones to store soft copies of various Mathematics textbooks which are often scarce in hard-copy form. Students also benefit from Mathematical applications that are installed in their smartphones. Teachers use smartphones as media in the classroom to enhance learner-understanding of the concepts. Again, in Chegato, the use of smartphones has exposed learners to various Mathematical technological skills that help in the learning of Mathematics and has the potential of improving the pass rate. School heads and teachers acknowledged that the availability of smartphones in the schools has greatly assisted “O” level Mathematics learners to accomplish their tasks.Strategies that can be used to enhance the use of smartphones in secondary schools include the use of individualised student passwords which are controlled and monitored by the school administrators to ensure that the activities of each learner on the Internet can be tracked and any attempts by students to visit undesirable sites are detected. Also, the use of software applications, such as Mikrotik Hotspot Blocker, can be used to block students from accessing unsavoury Internet sites. The study concluded that though challenges such as lack of technological resources and some educators’ negative attitudes towards the use of smart phones affect Chegato Cluster, most participants found it helpful to use smartphones in the classroom because the gadget expose learners to new and better ways of dealing with Mathematical concepts. The study finally calls for all the involved parties in the cluster and beyond to actively take up their responsibilities facilitating the use of smartphones for the benefits of the students.\u0000","PeriodicalId":503632,"journal":{"name":"Qeios","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141122930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paramount importance is given to the rotor's design; coupled with movable neodymium magnets to increase the harvester's life span and system's net revenue. For the amplification in the stator output, a cost-effective approach is adopted that is based on the parallel winding of the bifilar coil. Furthermore, the coefficient of performance factor for the Bedini's smart school girl circuit based electricity harvester is modified by aiding the concepts of radiant energy incorporated with the electromagnetic phenomenon. Moreover, the mathematical model is formulated by the Maxwell equations using the Lorenz gauge condition to capture free vacuum energy from the environment.

Esomeprazole magnesium trihydrate (EMT) is a proton pump inhibitor with reported antimicrobial activity, but its effects against efflux-mediated resistance are unknown.\u0000\u0000OBJECTIVE: To evaluate the antimicrobial activity of EMT alone and in combination with the efflux pump inhibitor reserpine against clinical isolates of _Pseudomonas aeruginosa, Acinetobacter baumannii_ and _Staphylococcus aureus_.\u0000\u0000METHODS: Minimum inhibitory concentration (MIC) assays were performed using the broth microdilution method on 15 non-duplicate clinical isolates and reference strains with/without EMT and reserpine.\u0000\u0000RESULTS: EMT demonstrated activity against all isolates, with MIC ranges of 4-32 μg/mL, 8-64 μg/mL and 2-16 μg/mL respectively. EMT MICs decreased 4-8-fold for 13/15 isolates when combined with reserpine, indicating EMT may inhibit efflux pumps. Similar reductions occurred for comparator antibiotics.\u0000\u0000CONCLUSIONS: This study provides the first evidence that EMT possesses intrinsic antimicrobial activity against these pathogens and may function as both an efflux pump substrate and inhibitor.
