There are dynamic processes operating that encourage the acceptance of new ideas and things, while there are others that encourage changeless stability. Despite the dramatic changes that have taken place in all human cultures, there are cultures still steadfast and resist change. These cultures resist through some culture mechanisms like, cultural boundaries, ethnocentrism, religion, and cultural relativity. So this paper is an attempt to discover these mechanisms of cultural change resistance and to ask is cultural change always required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20change" title="cultural change">cultural change</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20boundaries" title=" cultural boundaries"> cultural boundaries</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20relativity" title=" cultural relativity"> cultural relativity</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnocentrism" title=" ethnocentrism"> ethnocentrism</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a> </p> <a href="https://publications.waset.org/abstracts/44362/mechanisms-of-cultural-change-resistance-through-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5590</span> Integrating Cultures in Institutions of Higher Learning in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Mesatywa">N.

Thus, we aim to enhance students’ learning experiences by exploring and amalgamating both cultures for art creating. This text draws on our action research study of students’ visual literacy practices in a foundation sketching course in a major Chinese university, exploring art forms by cross-utilizing various cultural aspects. Instead of relying on the predominant western observational drawing skills in our classroom, we taught students about ancient Chinese art in the provincial museum, using Fu Hao owl-shaped vessel, a Shang Dynasty national treasure, as the final sketch project of this course. We took up multimodal literacy, which emphasized students’ critical use of creativity to exploit the semiotic potentials of communicative modes to address diverse cultural issues through their multimodal design. We used the Hong Kong-based artist Tik Ka’s artworks to demonstrate the cultural amalgamation of Chinese traditions and western pop cultures. Collectively, these approaches create a dialogical space for students to experience, analyze, and negotiate with complex modes and potentially transform their understanding of both cultures by redesigning Fu Hao. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinese%20traditions" title="Chinese traditions">Chinese traditions</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20pop%20cultures" title=" western pop cultures"> western pop cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu%20Hao" title=" Fu Hao"> Fu Hao</a>, <a href="https://publications.waset.org/abstracts/search?q=arts%20education" title=" arts education"> arts education</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20sketch" title=" design sketch"> design sketch</a> </p> <a href="https://publications.waset.org/abstracts/160082/fu-hao-from-the-east-between-chinese-traditions-and-western-pop-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5588</span> Evaluation of the Safety and Performance of Blood Culture Practices Using BD Safety-Lokᵀᴹ Blood Collection Sets in the Emergency Room</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeonghyun%20Chang">Jeonghyun Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Taegeun%20Lee"> Taegeun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Heungsup%20Sung"> Heungsup Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon-Seon%20Lee"> Yoon-Seon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn-Jung%20Kim"> Youn-Jung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Na%20Kim"> Mi-Na Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Safety device has been applied to improve safety and performance of blood culture practice. BD vacutainer® Safety-Lokᵀᴹ blood collection sets with pre-attached holder (Safety-Lok) (BD, USA) was evaluated in the emergency room (ER) of a tertiary care hospital. Methods: From April to June 2017, interns and nurses in ER were surveyed for blood culture practices with a questionnaire before and after 2 or 3 weeks of experience of Safety-Lok. All of them participated in exercise workshop for 1 hour combined with video education prior to the initial survey. The blood volume, positive and contamination rates of Safety-Lok-drawn (SD) blood cultures were compared to those of overall blood cultures. Results: Eighteen interns and 30 nurses were enrolled. As a result of the initial survey, interns had higher rates of needlestick incidence (27.8%), carriage of the blood-filled syringe with needle (88.9%) and lower rates of vacutainer use (38.9%) than nurses (13.3%, 53.3%, and 60.0%). Interns preferred to use safety devices (88.9%) rather than nurses (40.0%). The number of overall blood cultures and SD blood cultures was 9,053 and 555, respectively. While the overall blood volume of aerobic bottles was 2.6±2.1 mL, those of SD blood cultures were 5.0±3.0 mL in aerobic bottles and 6.0±3.0 mL in anaerobic bottles. Positive and contamination rates were 6.5% and 0.72% with SD blood cultures and 6.2% and 0.3% with overall blood cultures. Conclusions: The introduction of the safety device would encourage healthcare workers to collect adequate blood volume as well as lead to safer practices in the ER. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20culture" title="blood culture">blood culture</a>, <a href="https://publications.waset.org/abstracts/search?q=needlestick" title=" needlestick"> needlestick</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20device" title=" safety device"> safety device</a>, <a href="https://publications.waset.org/abstracts/search?q=volume" title=" volume"> volume</a> </p> <a href="https://publications.waset.org/abstracts/90313/evaluation-of-the-safety-and-performance-of-blood-culture-practices-using-bd-safety-lok-blood-collection-sets-in-the-emergency-room" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90313.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5587</span> Exploring Selected Cultures in Mitigating an Array of Social Vices in South Africa: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kang%27ethe%20Simon">M.

The article uses a review of literature methodology. Findings indicate that Africans were hoodwinked by white people to abandon their cultures for western based cultures. African cultures continue to weaken as they succumb to forces of westernization, eurocentrism, modernization, civilization, and globalization. Africans have realised that their cultures abandoned such as virginity testing, sexual mores and taboos and circumcision could be a panacea in mitigating some of the societal ills such as moral decadence and HIV/AIDS. The article urges for a resuscitation of cultural practices such as virginity testing, thigh sex (ukumetsha), circumcision and teachings that accompanied initiation schools; and societies to undergo an attitudinal and cultural paradigm shift that will consider the invaluable aspects of cultures that can effectuate and facilitate mitigation of social ills in African countries such as South Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virginity%20testing%20%28reed%20dance%29" title="virginity testing (reed dance)">virginity testing (reed dance)</a>, <a href="https://publications.waset.org/abstracts/search?q=circumcision" title=" circumcision"> circumcision</a>, <a href="https://publications.waset.org/abstracts/search?q=initiation%20schools" title=" initiation schools"> initiation schools</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20Renaissance" title=" African Renaissance"> African Renaissance</a>, <a href="https://publications.waset.org/abstracts/search?q=thigh%20sex" title=" thigh sex"> thigh sex</a>, <a href="https://publications.waset.org/abstracts/search?q=moral%20decadence" title=" moral decadence"> moral decadence</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20custodians" title=" cultural custodians"> cultural custodians</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20of%20anomie" title=" state of anomie"> state of anomie</a> </p> <a href="https://publications.waset.org/abstracts/11650/exploring-selected-cultures-in-mitigating-an-array-of-social-vices-in-south-africa-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">495</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5586</span> Crossing Borders: In Research and Business Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edith%20Podhovnik">Edith Podhovnik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cultures play a role in business communication and in research.

Multiple valuation inaccuracies are due to the unreliability of information used in valuation, inaccuracies comparison group selection, and use of individual multiple values. This study investigated the accuracy of valuation to examine factors that can increase the accuracy of the valuation of multiple ratios, that are discretionary accruals, the comparison group, and the composite of multiple valuation. These results indicate that multiple value adjustment method with discretionary accruals provides better accuracy, the industry comparator group method combined with the size and growth of companies also provide better accuracy. Composite of individual multiple valuation gives the best accuracy. If all of these factors combined, the accuracy of valuation of multiple ratios will give the best results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple" title="multiple">multiple</a>, <a href="https://publications.waset.org/abstracts/search?q=valuation" title=" valuation"> valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=accuracy" title=" accuracy"> accuracy</a> </p> <a href="https://publications.waset.org/abstracts/57424/improved-accuracy-of-ratio-multiple-valuation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57424.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">282</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5584</span> An Innovative Poly System Theory for the Go-Out of Chinese Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianhua%20Wang">Jianhua Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhou"> Ying Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Guo"> Han Guo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Translation underwent culture turn for more than half a century, which brought translation and its studies beyond intra-texts. Different cultures in recent years have developed towards a translation turn, which made a great contribution to relocate national or local cultures being localized to become regional or global cultures. As China grows quickly economically integrating into the world, it becomes urgent to relate China’s story and disseminate the Chinese culture. Due to the weaknesses and drawbacks of different existing cultural translation theories for Chinese culture to go out, a new perspective on translation turn for the go-out of Chinese culture should be drawn to spread better and disseminate Chinese culture to other countries. Based on the existing cultural translation theories, the equivalence of ideology, style of the translator and agency of the support are proposed to draw a new perspective: an innovative poly-system theory for Chinese culture translation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20translation%20theory" title="cultural translation theory">cultural translation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20culture" title=" Chinese culture"> Chinese culture</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20poly%20system" title=" innovative poly system"> innovative poly system</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20cultures" title=" global cultures"> global cultures</a> </p> <a href="https://publications.waset.org/abstracts/57358/an-innovative-poly-system-theory-for-the-go-out-of-chinese-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">453</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5583</span> Plant Cell Culture to Produce Valuable Natural Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jehad%20Dumireih">Jehad Dumireih</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Dmirieh"> Malak Dmirieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Wink"> Michael Wink</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is aimed to use plant cell suspension cultures of Crataegus monogyna for biosynthesis of valuable natural products by using quercetin as an inexpensive precursor. Suspension cell cultures of C. monogyna were established by using Murashige and Skoog medium (MS) supplemented with 1 mg/L 2,4-dichlorophenoxyacetic acid and 1 mg/L kinetin. Cells were harvested from the cultures and extracted by using methanol and ethyl acetate; then the extracts were used for the identification of isoquercetin by HPLC and by mass spectrometry. The incubation of the cells with 0.24 mM quercetin for one week resulted in an 16 fold increase of isoquercetin biosynthesis; the growth rate of the cells increased by 20%. Moreover, the biosynthesis of isoquercetin was enhanced by 40% when we divided the added quercetin into three portions each one with concentration 0.12 mM supplied at 3 days intervals. In addition, we didn’t find any positive effects of adding different concentrations the precursors phenylalanine (0.2 mM) and galactose to the cell cultures. In conclusion, the efficiency of the biotransformation of quercetin into isoquercetin depended on the concentration quercetin, its incubation time and the way of its administration. The results of the present work suggest that the biotechnological methods such as cell suspension cultures could be successfully used to obtain highly valuable natural product starting from inexpensive compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title="biosynthesis">biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=biotransformation" title=" biotransformation"> biotransformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Crataegus" title=" Crataegus"> Crataegus</a>, <a href="https://publications.waset.org/abstracts/search?q=isoquercetin" title=" isoquercetin"> isoquercetin</a> </p> <a href="https://publications.waset.org/abstracts/34551/plant-cell-culture-to-produce-valuable-natural-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34551.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5582</span> Comparative Survival Rates of Yeasts during Freeze-Drying, Traditional Drying and Spray Drying</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latifa%20Hamoudi-Belarbi">Latifa Hamoudi-Belarbi</a>, <a href="https://publications.waset.org/abstracts/search?q=L%27Hadi%20Nouri"> L'Hadi Nouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Belkacemi"> Khaled Belkacemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of three methods of drying (traditional drying, freeze-drying and spray-drying) on the survival of concentrated cultures of Geotrichum fragrans and Wickerhamomyces anomalus was studied. The survival of yeast cultures was initially compared immediately after freeze-drying using HES 12%(w/v)+Sucrose 7% (w/v) as protectant, traditional drying in dry rice cakes and finally spray-drying with whey proteins. The survival of G. fragrans and W. anomalus was studied during 4 months of storage at 4°C and 25°C, in the darkness, under vacuum and at 0% relative humidity. The results demonstrated that high survival was obtained using traditional method of preservation in rice cakes (60% for G. fragrans and 65% for W. anomalus) and freeze-drying in (68% for G. fragrans and 74% for W. anomalus). However, poor survival was obtained by spray-drying method in whey protein with 20% for G. fragrans and 29% for W. anomalus. During storage at 25°C, yeast cultures of G. fragrans and W. anomalus preserved by traditional and freeze-drying methods showed no significant loss of viable cells up to 3 months of storage. Spray-dried yeast cultures had the greatest loss of viable count during the 4 months of storage at 25°C. During storage at 4°C, preservation of yeasts cultures using traditional method of preservation provided better survival than freeze-drying. This study demonstrated the effectiveness of the traditional method to preserve yeasts cultures compared to the high cost methods like freeze-drying and spray-drying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=freeze-drying" title="freeze-drying">freeze-drying</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20drying" title=" traditional drying"> traditional drying</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=yeasts" title=" yeasts"> yeasts</a> </p> <a href="https://publications.waset.org/abstracts/26630/comparative-survival-rates-of-yeasts-during-freeze-drying-traditional-drying-and-spray-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26630.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">490</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5581</span> The Effect of Antibiotic Use on Blood Cultures: Implications for Future Policy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avirup%20Chowdhury">Avirup Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Angus%20K.%20McFadyen"> Angus K.

However, while the current literature outlines indications for initial BCs to be taken, there is little guidance for repeat sampling in the following 5-day period and little information on how antibiotic use can affect the usefulness of this investigation. A retrospective cohort study was conducted using inpatients who had undergone 2 or more BCs within 5 days between April 2016 and April 2017 at a 400-bed hospital in the west of Scotland and received antibiotic therapy between the first and second BCs. The data for BC sampling was collected from the electronic microbiology database, and cross-referenced with data from the hospital electronic prescribing system. Overall, 283 BCs were included in the study, taken from 92 patients (mean 3.08 cultures per patient, range 2-10). All 92 patients had initial BCs, of which 83 were positive (90%). 65 had a further sample within 24 hours of commencement of antibiotics, with 35 positive (54%). 23 had samples within 24-48 hours, with 4 (17%) positive; 12 patients had sampling at 48-72 hours, 12 at 72-96 hours, and 10 at 96-120 hours, with none positive. McNemar’s Exact Test was used to calculate statistical significance for patients who received blood cultures in multiple time blocks (Initial, < 24h, 24-120h, > 120h). For initial vs. < 24h-post BCs (53 patients tested), the proportion of positives fell from 46/53 to 29/53 (one-tailed P=0.002, OR 3.43, 95% CI 1.48-7.96). For initial vs 24-120h (n=42), the proportions were 38/42 and 4/42 respectively (P < 0.001, OR 35.0, 95% CI 4.79-255.48). For initial vs > 120h (n=36), these were 33/36 and 2/36 (P < 0.001,OR ∞). These were also calculated for a positive in initial or < 24h vs. 24-120h (n=42), with proportions of 41/42 and 4/42 (P < 0.001, OR 38.0, 95% CI 5.22-276.78); and for initial or < 24h vs > 120h (n=36), with proportions of 35/36 and 2/36 respectively (P < 0.001, OR ∞). This data appears to show that taking an initial BC followed by a BC within 24 hours of antibiotic commencement would maximise blood culture yield while minimising the risk of false negative results. This could potentially remove the need for as many as 46% of BC samples without adversely affecting patient care. BC yield decreases sharply after 48 hours of antibiotic use, and may not provide any clinically useful information after this time. Further multi-centre studies would validate these findings, and provide a foundation for future health policy generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title="antibiotics">antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20culture" title=" blood culture"> blood culture</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=inpatient" title=" inpatient"> inpatient</a> </p> <a href="https://publications.waset.org/abstracts/82846/the-effect-of-antibiotic-use-on-blood-cultures-implications-for-future-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82846.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5580</span> A More Powerful Test Procedure for Multiple Hypothesis Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shunpu%20Zhang">Shunpu Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a new multiple test called the minPOP test for testing multiple hypotheses simultaneously.

The significance of cross-cultural negotiations lies in the fact that many business relationships have already failed due to the lack of cultural knowledge. Therefore, the paper deals with cross-cultural negotiations in case of Hungarian business negotiators. The aim of the paper is to introduce the findings of a two-phase research conducted among Hungarian business negotiators. In the first phase a qualitative research was conducted to reveal the importance of cultural differences in case of cross-cultural business negotiations from the viewpoint of Hungarian negotiators, whereas in the second phase a quantitative one was conducted to figure out whether cultural stereotypes affect the way how the respondents negotiate with people coming from different cultures. The research found out that in case of Hungarian negotiators it is mostly the lack of cultural knowledge that lurks behind the problems and miscommunication occurring during the negotiations. The research also revealed that stereotypes have an influence on the negotiation styles of Hungarian negotiators. The paper concludes that culture and cultural differences must be taken into consideration in case of cross-cultural negotiations so that problems and misunderstandings could be avoided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business" title="business">business</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=negotiations" title=" negotiations"> negotiations</a>, <a href="https://publications.waset.org/abstracts/search?q=stereotypes" title=" stereotypes"> stereotypes</a> </p> <a href="https://publications.waset.org/abstracts/94244/negotiating-across-cultures-the-case-of-hungarian-negotiators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94244.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5578</span> The Influence of Colloidal Metal Nanoparticles on Growth and Proliferation of in Vitro Cultures of Potato</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Przewodowski%20W%C5%82odzimierz">Przewodowski Włodzimierz</a>, <a href="https://publications.waset.org/abstracts/search?q=Przewodowska%20Agnieszka"> Przewodowska Agnieszka</a>, <a href="https://publications.waset.org/abstracts/search?q=Sekrecka%20Danuta"> Sekrecka Danuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Micha%C5%82owska%20Dorota"> Michałowska Dorota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Colloidal metal nanoparticles are widely applied in various areas and have great potential in different biotechnological applications. Their particular properties associated with both the antiseptic, antioxidant and anti aging properties as well as ability to penetrate most of the biological barriers, synergy in the absorption of nutrients and nontoxic to plants. The properties make them potentially useful in the fast and safe production of healthy, certified starting material in the production of plants exposed to many pathogenic microorganisms causing serious diseases, significantly affecting yield and causing the economic losses. In this case it is crucial to provide appropriate conditions for the production, storage and distribution of the plant material. Therefore, the aim of the proposed research was to develop and identify the influence of four colloidal metal nanoparticles on growth and proliferation of in vitro cultures of potato (Solanum tuberosum) - one of the most economically important strategic crops in the world. The research on different varieties of potato was performed by placing the explants of the in vitro cultures on sterile Murashige and Skoog (MS) type medium. The influence of the nanocolloids was evaluated using the MS medium impregnated with the examinated nanoparticles. The vigour of growth and the rate of proliferation was examinated for 6-8 weeks with both night/day-length and temperature over the ranges 8/16 h and 20–22 °C respectively. The results of our preliminary work confirmed high usefulness of the nanocolloids in the safe production of the examinated in vitro cultures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colloidal%20metal%20nanoparticles" title="colloidal metal nanoparticles">colloidal metal nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20cultures" title=" in vitro cultures"> in vitro cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=potato" title=" potato"> potato</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation" title=" propagation"> propagation</a> </p> <a href="https://publications.waset.org/abstracts/47259/the-influence-of-colloidal-metal-nanoparticles-on-growth-and-proliferation-of-in-vitro-cultures-of-potato" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5577</span> Implementing Teacher Students’ Coaching in Practical Periods of University Teacher Education: The Significance of Training Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahm%20Sibylle">Rahm Sibylle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The core element in most European teacher training concepts consists in practical periods where teacher students may review the chosen profession before going on to their theoretical studies. In Germany, teacher students learn in practical studies about everyday teaching and learning in schools. Teacher students appreciate opportunities to explore school practice and to feel responsible for students’ learning. In practical studies, teacher students often idealize their teacher mentors (and consequently tend to imitate their teaching style) or contrarily feel disappointed about school practice. Concepts of empowerment through practical experience in school-based academic teacher training have to be developed. Our Swiss-German research project COPRA (Coaching in practical periods; funded by the Swiss National Science Foundation (SNF) and the German Research Foundation (DFG), aims at gaining resilient results about the effectiveness of (peer) coaching in practical school periods. To explore innovative ways of accompanying novice teachers in practical periods we consider different cultures of teacher training institutions. School cultures, including teachers’ beliefs and teaching traditions involve different training cultures as starting positions for our intervention study. In our qualitative study, we describe typologies of teacher training institutions by analyzing group discussions with teacher students, mentor teachers and university lecturers concerning participation, cooperation, and relationships. In our paper, we present the design of our intervention study, our coaching concept as well as typologies of teacher training cultures. We discuss opportunities for teacher students to learn through domain-specific (peer) coaching on the background of these typologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teacher%20training%20%28practical%20periods%29" title="teacher training (practical periods)">teacher training (practical periods)</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20students%27%20coaching" title=" teacher students' coaching"> teacher students' coaching</a>, <a href="https://publications.waset.org/abstracts/search?q=training%20cultures%20%28typologies%29" title=" training cultures (typologies)"> training cultures (typologies)</a>, <a href="https://publications.waset.org/abstracts/search?q=COPRA%20%28coaching%20in%20practical%20periods%29" title=" COPRA (coaching in practical periods)"> COPRA (coaching in practical periods)</a> </p> <a href="https://publications.waset.org/abstracts/69867/implementing-teacher-students-coaching-in-practical-periods-of-university-teacher-education-the-significance-of-training-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5576</span> Evaluation of DNA Microarray System in the Identification of Microorganisms Isolated from Blood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merih%20%C5%9Eim%C5%9Fek">Merih Şimşek</a>, <a href="https://publications.waset.org/abstracts/search?q=Recep%20Ke%C5%9Fli"> Recep Keşli</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCl%20%C3%87etinkaya"> Özgül Çetinkaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Demir"> Cengiz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Adem%20Aslan"> Adem Aslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacteremia is a clinical entity with high morbidity and mortality rates when immediate diagnose, or treatment cannot be achieved. Microorganisms which can cause sepsis or bacteremia are easily isolated from blood cultures. Fifty-five positive blood cultures were included in this study. Microorganisms in 55 blood cultures were isolated by conventional microbiological methods; afterwards, microorganisms were defined in terms of the phenotypic aspects by the Vitek-2 system. The same microorganisms in all blood culture samples were defined in terms of genotypic aspects again by Multiplex-PCR DNA Low-Density Microarray System. At the end of the identification process, the DNA microarray system’s success in identification was evaluated based on the Vitek-2 system. The Vitek-2 system and DNA Microarray system were able to identify the same microorganisms in 53 samples; on the other hand, different microorganisms were identified in the 2 blood cultures by DNA Microarray system. The microorganisms identified by Vitek-2 system were found to be identical to 96.4 % of microorganisms identified by DNA Microarrays system. In addition to bacteria identified by Vitek-2, the presence of a second bacterium has been detected in 5 blood cultures by the DNA Microarray system. It was identified 18 of 55 positive blood culture as E.coli strains with both Vitek 2 and DNA microarray systems. The same identification numbers were found 6 and 8 for Acinetobacter baumanii, 10 and 10 for K.pneumoniae, 5 and 5 for S.aureus, 7 and 11 for Enterococcus spp, 5 and 5 for P.aeruginosa, 2 and 2 for C.albicans respectively. According to these results, DNA Microarray system requires both a technical device and experienced staff support; besides, it requires more expensive kits than Vitek-2. However, this method should be used in conjunction with conventional microbiological methods. Thus, large microbiology laboratories will produce faster, more sensitive and more successful results in the identification of cultured microorganisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microarray" title="microarray">microarray</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitek-2" title=" Vitek-2"> Vitek-2</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20culture" title=" blood culture"> blood culture</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteremia" title=" bacteremia"> bacteremia</a> </p> <a href="https://publications.waset.org/abstracts/72604/evaluation-of-dna-microarray-system-in-the-identification-of-microorganisms-isolated-from-blood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72604.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5575</span> The Development and Future of Hong Kong Typography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amic%20G.%20Ho">Amic G.

In contrast to many other parts of the world, where there is only one language, in Hong Kong many signs and billboards display two languages: Chinese and English. The language usage on signage, fonts and types used, and the designs in magazines and advertisements all demonstrate the unique features of Hong Kong typographic design, which reflect the multicultural nature of Hong Kong society. This study is the first step in investigating the nature and development of Hong Kong typography. The preliminary research explored how the historical development of Hong Kong is reflected in its unique typography. Following a review of historical development, a quantitative study was designed: Local Hong Kong participants were invited to provide input on what makes the Hong Kong typographic style unique. Their input was collected and analyzed. This provided us with information about the characteristic criteria and features of Hong Kong typography, as recognized by the local people. The most significant typographic designs in Hong Kong were then investigated and the influence of Chinese and other cultures on Hong Kong typography was assessed. The research results provide an indication to local designers on how they can strengthen local design outcomes and promote the values and culture of their mother town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=typography" title="typography">typography</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Kong" title=" Hong Kong"> Hong Kong</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20developments" title=" historical developments"> historical developments</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20cultures" title=" multiple cultures"> multiple cultures</a> </p> <a href="https://publications.waset.org/abstracts/51218/the-development-and-future-of-hong-kong-typography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51218.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5574</span> Early Cell Cultures Derived from Human Prostate Cancer Tissue Express Tissue-Specific Epithelial and Cancer Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Ryabov">Vladimir Ryabov</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Baryshevs"> Mikhail Baryshevs</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Voskresenskey"> Mikhail Voskresenskey</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20Popov"> Boris Popov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The human prostate gland (PG) samples were obtained from patients who had undergone radical prostatectomy for prostate cancer (PC) and used to extract total RNA and prepare the prostate stromal cell cultures (PSCC) and patients-derived organoids (PDO). Growth of the cell cultures was accessed under microscopic evaluation in transmitted light and the marker expression by reverse polymerase chain reaction (RT-PCR), immunofluorescence, and immunoblotting. Some PCR products from prostate tissue, PSCC, and PDO were cloned and sequenced. We found that the cells of early and late passages of PSCC and corresponding PDO expressed luminal (androgen receptor, AR; cytokeratin 18, CK18) and basal (CK5, p63) epithelial markers, the production of which decreased or disappeared in late PSCC and PDO. The PSCC and PDO of early passages from cancer tissue additionally produced cancer markers AMACR, TMPRSS2-ERG, and Ezh2. The expression of TMPRSS2-ERG fusion transcripts was verified by cloning and sequencing the PCR products. The results obtained suggest that early passages of PSCC might be used as a pre-clinical model for the evaluation of early markers of prostate cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=localized%20prostate%20cancer" title="localized prostate cancer">localized prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20epithelial%20markers" title=" prostate epithelial markers"> prostate epithelial markers</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer%20markers" title=" prostate cancer markers"> prostate cancer markers</a>, <a href="https://publications.waset.org/abstracts/search?q=AMACR" title=" AMACR"> AMACR</a>, <a href="https://publications.waset.org/abstracts/search?q=TMPRSS2-ERG" title=" TMPRSS2-ERG"> TMPRSS2-ERG</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20stromal%20cell%20cultures" title=" prostate stromal cell cultures"> prostate stromal cell cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=PDO" title=" PDO"> PDO</a> </p> <a href="https://publications.waset.org/abstracts/153032/early-cell-cultures-derived-from-human-prostate-cancer-tissue-express-tissue-specific-epithelial-and-cancer-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153032.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5573</span> The Contemporary Visual Spectacle: Critical Visual Literacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lai-Fen%20Yang">Lai-Fen Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this increasingly visual world, how can we best decipher and understand the many ways that our everyday lives are organized around looking practices and the many images we encounter each day?

The parasite responsible for the vast majority of fatal malaria infections is Plasmodium falciparum. Unfortunately, most Plasmodium strains including P. falciparum have become resistant to most of the antimalarials including chloroquine, mefloquine, etc. To combat this problem, WHO has recommended the use of artemisinin and its derivatives in artemisinin based combination therapy (ACT). Due to its current use in artemisinin based-combination therapy (ACT), its global demand is increasing continuously. But, the relatively low yield of artemisinin in A. annua L. plants and unavailability of economically viable synthetic protocols are the major bottlenecks for its commercial production and clinical use. Chemical synthesis of artemisinin is also very complex and uneconomical. The hairy root system, using the Agrobacterium rhizogenes LBA 9402 strain to enhance the production of artemisinin in A. annua L., is developed in our laboratory. The transgenic nature of hairy root lines and the copy number of trans gene (rol B) were confirmed using PCR and Southern Blot analyses, respectively. The effect of different concentrations of Piriformospora indica on artemisinin production in hairy root cultures were evaluated. 3% P. indica has resulted 1.97 times increase in artemisinin production in comparison to control cultures. The effects of P. indica on artemisinin production was positively correlated with regulatory genes of MVA, MEP and artemisinin biosynthetic pathways, viz. hmgr, ads, cyp71av1, aldh1, dxs, dxr and dbr2 in hairy root cultures of A. annua L. Mass scale cultivation of A. annua L. hairy roots by plant tissue culture technology may be an alternative route for production of artemisinin. A comprehensive investigation of the hairy root system of A. annua L. would help in developing a viable process for the production of artemisinin. The efficiency of the scaling up systems still needs optimization before industrial exploitation becomes viable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20annua%20L." title="A. annua L.">A. annua L.</a>, <a href="https://publications.waset.org/abstracts/search?q=artemisinin" title=" artemisinin"> artemisinin</a>, <a href="https://publications.waset.org/abstracts/search?q=hairy%20root%20cultures" title=" hairy root cultures"> hairy root cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=malaria" title=" malaria"> malaria</a> </p> <a href="https://publications.waset.org/abstracts/22980/improvement-of-artemisinin-production-by-p-indica-in-hairy-root-cultures-of-a-annua-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5570</span> Personal Identity and Group Identity under Threat following Exclusion: A Study in Singapore and in the Netherlands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20N.%20Huwa%C3%AB">Z.

In doing so, they investigated whether threatened identities depend on whether people are excluded by ingroup members (same ethnic background) or outgroup members (another ethnic background), as exclusion studies have shown mixed results when it comes to being excluded by ingroup versus outgroup members. For this purpose, students in Singapore and in the Netherlands participated in an online ball-tossing game (Cyberball) where they were excluded or included by other players with either the same or other ethnicity. Tentative results showed that both Singaporean and Dutch participants reported a more threat to their group identity than to their personal identity following exclusion and this did not depend on who excluded them. These tentative findings suggest that threatened identities following exclusion may not depend on cultural factors or on the source of exclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultures" title="cultures">cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=exclusion" title=" exclusion"> exclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20membership" title=" group membership"> group membership</a>, <a href="https://publications.waset.org/abstracts/search?q=identities" title=" identities"> identities</a> </p> <a href="https://publications.waset.org/abstracts/123621/personal-identity-and-group-identity-under-threat-following-exclusion-a-study-in-singapore-and-in-the-netherlands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5569</span> Components of Effective Learning Environments: Global Perspectives on Student Perceptions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Appatova">Victoria Appatova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> internal and external, that are largely shaped by the student’s perceptions. Since 2006, the ELE concept has been studied by an international group of scholars through the creation of an ELE survey which was administered in nine countries and translated into five languages. The survey compares students’ perceptions of their learning environments and self-efficacy across A student’s effective learning environment (ELE) is comprised of multiple factors, both cultures as well as distinguishes similarities and differences in the students’ needs related to their learning. The main objectives of this international project include the following: Determine a system of components constituting ELE from the perspective of students and other academic populations Analyze students’ expectations, and their chances to succeed in college based on their expectations Conceptualize a comprehensive approach for assessing the effectiveness of a learning environment Compare the actualization of the ELE concept in American schools versus other national educational systems Compare student perceptions of ELE with those of faculty, administrators, and professional staff Four major factors influencing student learning across cultures and various national educational systems were determined: students’ initiative in using support services; learning skills; external comfort; and curriculum. Recent changes in the students’ perceptions, resulting from technology advances and a rapid shift to online learning, are being explored.

The study's objectives included investigating culturally relevant instructional techniques, strategies, and technologies for the Itaukei (Indigenous Fijian) and ni-Vanuatu cultures, enhancing appreciation for culturally sensitive pedagogical methods. Methodologically, a qualitative inquiry phenomenological approach was employed within a constructivist paradigm, utilizing a comprehensive qualitative scoping review and online literature search. Key findings include the prioritization of cultural inclusivity and indigenous knowledge integration in both indigenous education philosophies and various instructional approaches. Learner-centered methods like constructivist andragogy and the learning cycle are applicable and effective in distance education within these cultures, aligning with indigenous learners' values and preferences. Place-based education and critical pedagogy of place are particularly pertinent, fostering a deeper connection between education, local environments, and social justice. Integrating digital technologies in culturally responsive education bridges geographical gaps and preserves cultural knowledge. Lastly, blending Western and Indigenous Science, influenced by a Two-Eyed Seeing approach, informs pedagogy by combining Western and Indigenous Science. This research underscores the importance of acknowledging cultural diversity and respecting indigenous knowledge in distance education. It highlights the value of learner-centered approaches, place-based education, and technology integration. The study enriches the educational experience within the Itaukei and niVanuatu cultures and provides insights for educators and policymakers aiming to bridge cultural gaps in distance education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20pedegory%20of%20place" title="critical pedegory of place">critical pedegory of place</a>, <a href="https://publications.waset.org/abstracts/search?q=Itaukei%20%28indigenous%20Fijian%29%20and%20ni-Vanuatu%20cultures" title=" Itaukei (indigenous Fijian) and ni-Vanuatu cultures"> Itaukei (indigenous Fijian) and ni-Vanuatu cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=placed-based%20education" title=" placed-based education"> placed-based education</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20knowledge" title=" indigenous knowledge"> indigenous knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20education" title=" distance education"> distance education</a> </p> <a href="https://publications.waset.org/abstracts/189434/bridging-cultures-in-distance-education-a-confluence-of-critical-pedagogy-of-place-and-indigenous-education-philosophy-case-study-reference-in-fiji-and-vanuatu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">18</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5567</span> Online Language Tandem: Focusing on Intercultural Communication Competence and Non-Verbal Cues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Benabdelkader">Amira Benabdelkader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Communication presents the channel by which humankind create and maintain their relationship with others, express themselves, exchange information, learn and teach etc. The context of communication plays a distinctive role in deciding about the language to be used. The term context is mainly used to refer to the interlocutors, their cultures, languages, relationship, physical surrounding that is the communication setting, type of the information to be transmitted, the topic etc. Cultures, on one hand, impose on humans certain behaviours, attitudes, gestures and beliefs. On the other hand, the focus on language is inevitable as it is with its verbal and non-verbal components, a key tool in and for communication. Moreover, each language has its particularity in how people voice, address and express their thoughts, feelings and beliefs. Being in the same setting with people from different cultures and languages and having conversations with them would call upon the intercultural communicative competence. This latter would promote the success of their conversations. Additionally, this competence could manifest in several ways during their interactions, to the extent that no one can predict when and how the interlocutors would use it. The only thing probably that could be confirmed is that the setting and culture would in a way or another intervene and often shape the flow of their communication, if not the whole communication. Therefore, this paper will look at the intercultural communicative competence of language learners when introducing their cultures to each other in an online language tandem (henceforth OLT) using their second and/or foreign language with the L1 language speakers. The participants of this study are Algerian (use L2: French, FL: English), British (L1: English, L2/FL: French). In other words, this current paper will provide a qualitative analysis of the OLT experiment by emphasising how language learners can overcome the cultural differences in an intercultural setting while communicating online using Skype (video conversations) with people from different countries, cultures and L1. The non-verbal cues will have the lion share in the analysis by focusing on how they have been used to maintain this intercultural communication or hinder it through the misinterpretation of gestures, head movements, grimaces etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intercultural%20communicative%20competence" title="intercultural communicative competence">intercultural communicative competence</a>, <a href="https://publications.waset.org/abstracts/search?q=non-verbal%20cues" title=" non-verbal cues"> non-verbal cues</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20language%20tandem" title=" online language tandem"> online language tandem</a>, <a href="https://publications.waset.org/abstracts/search?q=Skype" title=" Skype"> Skype</a> </p> <a href="https://publications.waset.org/abstracts/65461/online-language-tandem-focusing-on-intercultural-communication-competence-and-non-verbal-cues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65461.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5566</span> Acculturation Profiles of Syrian Refugees in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdurrahim%20Guler">Abdurrahim Guler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Immigrants who came to a new country experience some socio-cultural difficulties which are different from theirs. The study aims to investigate how Syrian Refugees manage their life in Turkey and the relationship between acculturation profiles and demographic background of Syrian refugees who came to Turkey after civil war has intensified in Syria. Data are collected from 280 adult Syrian refugees who were born in Syria. The study adopts bi-dimensional acculturation approach stating that both heritage and dominant host cultures can live together. Results suggest that demographic backgrounds, religion, and religiosity are significantly linked to both heritage and dominant host culture. Syrian refugees who are not affiliated with Islam are found to significantly preserve their ethnic/heritage culture. Generally, Syrian refugees are more willing to integrate Turkish society but not to assimilate. The results also confirmed acculturation process as a bi-dimensional, not a zero-sum game since we found a significant positive correlation between the heritage and the dominant host cultures which assume the independence and orthogonal of involvements in the dominant host and heritage cultures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acculturation" title="acculturation">acculturation</a>, <a href="https://publications.waset.org/abstracts/search?q=demographic%20backgrounds" title=" demographic backgrounds"> demographic backgrounds</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20culture" title=" heritage culture"> heritage culture</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a>, <a href="https://publications.waset.org/abstracts/search?q=Syrian%20refugees" title=" Syrian refugees"> Syrian refugees</a> </p> <a href="https://publications.waset.org/abstracts/75355/acculturation-profiles-of-syrian-refugees-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5565</span> Cultural Differences in Gender Stereotyping of Leaders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Clapham">Maria Clapham</a>, <a href="https://publications.waset.org/abstracts/search?q=Krysta%20Thomason"> Krysta Thomason</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examined how age and gender of a leader affect characterizations of leaders across cultures.

The multiple vertical plunging jets have jet impact angle of θ = 90O; whereas, multiple inclined plunging jets have jet impact angle of θ = 600. The results of the study suggests that mass transfer is higher for multiple jets, and inclined multiple plunging jets have up to 1.6 times higher mass transfer than vertical multiple plunging jets under similar conditions. The derived relationship, based on multi-linear regression approach, has successfully predicted the volumetric mass transfer coefficient (KLa) from operational parameters of multiple plunging jets with a correlation coefficient of 0.973, root mean square error of 0.002 and coefficient of determination of 0.946. The results suggests that predicted overall mass transfer coefficient is in good agreement with actual experimental values; thereby suggesting the utility of derived relationship based on multi-linear regression based approach and can be successfully employed in modelling mass transfer by multiple plunging jets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mass%20transfer" title="mass transfer">mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20plunging%20jets" title=" multiple plunging jets"> multiple plunging jets</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-linear%20regression" title=" multi-linear regression"> multi-linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20sciences" title=" earth sciences"> earth sciences</a> </p> <a href="https://publications.waset.org/abstracts/5905/multi-linear-regression-based-prediction-of-mass-transfer-by-multiple-plunging-jets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5905.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5563</span> The Dual Role of the Internet in the Development of Local Communities Through Ecotourism and Cultural Assimilation in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haniyeh%20Sameie">Haniyeh Sameie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the process of globalization, geographical boundaries gradually lose their importance, and ethnic, local, and regional cultures are integrated with each other and even marginalized. Globalization has many manifestations and aspects, including economic, political, social, etc., but this paper has focused on the cultural aspect of globalization. From this point of view, one of the important issues that have always been raised is the assimilation of diverse and plural cultures, which are gradually disappearing and destroyed in the onslaught of global culture and are dissolved in global culture. In the postmodern paradigm, the tools of the globalized world can be used to preserve and strengthen cultural diversity. For example, the Internet, as a globalization tool, can play an important role in preserving and recognizing local cultures. In today's world, the world nations and ethnic groups are trying to revive their specific and native cultures in different ways in opposition to the rising cultural assimilation and challenge the globalization of culture. One of the manifestations of these actions is addressing the issue of tourism and, specifically, eco-tourism, which is being developed in Iran as well as in other parts of the world, relying on the powerful tool of globalization, the Internet. Considering the significant growth of the ecotourism industry in Iran in recent years, this paper focuses on the role of the Internet in the development of ecotourism in Iran as one of the manifestations of tourism in recent decades and how to preserve and survive diverse local cultures and strengthen local communities against global culture through it. One of the major challenges in the development of communication technology in Iran in the last decade has been the debate over the necessity or non-necessity of access to high-speed Internet in the villages of Iran. Some believe that accessing the broadband internet in the villages may lead to the disappearance of local cultures and can facilitate the spread of western culture among villagers. On the other hand, the speed of expansion of ecotourism in Iran in the last ten years is owed to the development of the Internet in villages. In this regard, we pay attention to the dual role of the Internet in cultural assimilation and, at the same time, the platform that the online space has created for the growth and development of ecotourism accommodations as a source of stable income for local communities, focusing on the Iranian experience in the recent decade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tourism" title="tourism">tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=internet" title=" internet"> internet</a>, <a href="https://publications.waset.org/abstracts/search?q=ecotourism%20in%20Iran" title=" ecotourism in Iran"> ecotourism in Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20assimilation" title=" cultural assimilation"> cultural assimilation</a> </p> <a href="https://publications.waset.org/abstracts/165163/the-dual-role-of-the-internet-in-the-development-of-local-communities-through-ecotourism-and-cultural-assimilation-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5562</span> Implications of Oxidative Stress for Monoterpenoid Oxindole Alkaloid Production in Uncaria tomentosa Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20C.%20Ramos%20Valdivia">Ana C.

Huerta-Heredia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The conditions of biotic and abiotic stress in plants can lead to the generation of high amounts of reactive oxygen species (ROS), which leads through a signaling cascade and second messengers to different antioxidant defense responses including the production of secondary metabolites. A limited number of species of plants like Uncaria tomentosa (cat claw) typical of the Amazon region produce monoterpenoid oxindole alkaloids (MOA) such as isopteropodine, mitraphylline, rhynchophylline and its isomers. Moreover, in cultivated roots, the glucoindole alkaloid 3α-dihydrocadambine (DHC) is also accumulated. Several studies have demonstrated that MAO has antioxidant properties and possess important pharmacological activities such as antitumor and immunostimulant while DHC, has hypotensive and hypolipidemic effects. In order the study the regulatory concerns operating in MAO production, the links between oxidative stress and antioxidant alkaloid production in U. tomentosa root cultures were examined. Different amount of hydrogen peroxide between 0.2 -1.0 mM was added to 12 days old roots cultures showing that, this substance had a differential effect on the production of DHC and MOA whereas the viability remained in 80% after six days. Addition of 0.2 mM hydrogen peroxide increased approximately 65% MAO and DHC production (0,540 ± 0.018 and 0.618 ± 0.029 mg per g dry weight, respectively) relative to the control. On contrast, after the addition of 0.6 mM and 1 mM hydrogen peroxide, DHC accumulation into the roots gradually decreased to 53% and 93% respectively, without changes in MAO concentration, which was in relation to a twice increase of the intracellular hydrogen peroxide content. On the other hand, concentrations of DHC (0.1, 0.5 and 1.0 mM in methanol) demonstrated free-radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The calculated IC50 for all tested concentrations was 0.180 mg per ml (0.33 mM) while the calculated TE50 was 276 minutes. Our results suggest that U. tomentosa root cultures both MAO and DHC have antioxidant capacities and respond to oxidative stress with a stimulation of their production; however, in presence of a higher concentration of ROS into the roots, DHC could be oxidized. <p class="card-text"><strong>Keywords:</strong> <a
