The Relationship

The graphite oxidation of fuel element has obtained high attention in air ingress accident analysis of high temperature gas-cooled reactor (HTR). The shape function, defined as the relationship between the maximum and the average of the oxidation, is an important factor to estimate the consequence of the accident. There are no detailed studies on the shape function currently except two experiments several decades ago. With the development of computer technology, CFD method is used in the numerical experiment about graphite oxidation in pebble bed of HTR in this paper. Structured packed beds are used in the calculation instead of random packed beds. The result shows the nonuniform distribution of oxidation on the sphere surface and the shape function in the condition of air ingress accident. Furthermore, the sensitive factors of shape function, such as temperature and Re number, are discussed in detail and the relationship between the shape function and sensitive factors is explained. According to the results in this paper, the shape function ranges from 1.05 to 4.7 under the condition of temperature varying from 600°C to 1200°C and Re varying from 16 to 1600.

Situational Test

Advances in computer technology have created opportunities for the development of a multimedia situational test in which responses are filmed with a webcam. This paper examined the relationship of a so-called webcam test with personality, cognitive ability, job experience, and academic performance. Data were collected among 153 psychology students. In line with our expectations, scores on the webcam test, intended to measure interpersonally oriented leadership, were related to extraversion, conscientiousness, emotional stability, and job experience. Furthermore, the webcam tests significantly predicted students’ learning activities during group meetings over and above a cognitive ability test and a personality questionnaire. Overall, this study demonstrates that webcam tests can be a valid complement to traditional predictors in selection contexts.

ÖZET. Milletlerin çok eski zamanlardan bugüne kadar yaşayarak edinmiş oldukları tecrübeler, bilgiler, kazanımlar ve değerler o milletin kültürünü oluşturur. Edinilen değerlerin dil aracılığıyla hayat bulması kültürdilbilim alanı çerçevesinde kültür-dil-insan arasındaki ilişkiyi incelemeye değer bulmuştur. Herhangi bir varlığın şekline, işlevine, görevine, görüntüsüne her toplumda farklı anlam veya dilsel dünya görüşünü yansıtan adlar verilir. Kültür-dil-insan çerçevesinde dil ve kültür ilişkilerinin belli bir disiplin altında incelenmesi ancak kültürdilbilim yoluyla mümkündür. Dilbilim alanına ait kültürdilbilim çalışmalarında ele alınan dilsel dünya görüşü kavramı her bir dilin dolayısıyla toplumun ya da ortak değerlere sahip toplumlarının oluşturduğu milletlerin dünyayı nasıl algılayıp yansıttığını, çevresindeki varlıkların ve kavramların hangi niteliklerini ayırt ettiğini, insanın duygu ve düşüncelerini, değer yargılarını nasıl betimledikleri incelenmektedir. Bu makalede kültürdilbilim çerçevesinde Türkçede “gibi”, Kırgızcada -DAy eki ve “sıyaktuu”, “öndüü” bağlacıyla yapılan benzetmeler ve deyimler Türkçe ile karşılaştırmalı olarak incelenmekte, böylelikle iki toplum arasındaki dış dünya algısı arasındaki farklılıklar veya benzerlikler tespit edilecektir. Адам баласы алмустактан бери топтогон маалыматы, турмуштан топтогон тажрыйбасы жана баалуулуктары менен улуттук маданиятын түзгөн. Тилдик каражаттар аркылуу чагылдырылган турмуштук тажрыйбалар улуттук маданият чөлкөмүндө маданият-тил-адам баласы деген чөйрөдө изилдөөгө алынат. Сөз, форма, иш аракет, көрүнүштөр ар бир коомдо ар кандай маанини туюндурган лексикалар менен берилген. Маданият-тил-адам баласы аттуу чөйрөдө тилдик жана маданий байланыштар белгилүү бир тартипте изилдениши бир гана маданияттаануу жолу менен ишке ашат. Тил илимине тиешелүү маданияттаануу илиминде каралган тилдик дүйнө тааным түшүнүгү ар бир тилдин, ошол эле учурда орток баалуулуктарга ээ болгон коомдун дүйнөнү кабыл алышы жана аны чагылдырышы, анын чөйрөнү жана түшүнүктөрдү айырмалаган сапаттарын, адамдын ички уйгу-туйгусун жана түшүнүктөрүн кандай сүрөттөгөнүн изилденет. Бул макалада маданияттаанууда Түрк тилиндеги “gibi” Кыргыз тилиндеги –ДАй мүчөсү, сыяктуу жана өндүү жандоочтор менен бе-рилиши, фразеологиялык каражаттар Түрк тили менен салыштырылып, эки тилдин ортосундагы сырткы дүйнө тааным менен болгон айырмасы жана окшоштуктары аныкталат. The experiences, knowledge, achievements and values that have been gained by nations starting from ancient times and up today constitute the culture of that nation. It has become worthy of examining the relationship between culture-language-human within the frameworks of cultural linguistics. Names are attached to any entity in accordance with its shape, function, tasks, and appearance that reflect different meanings in each society or their linguistic worldview. Analyzing language and culture relations within the scope of a certain discipline in the frameworks of culture-language-human is only possible by means of Cultural Linguistics. The concept of linguistic worldview, which is discussed in cultural-linguistics studies in the field of linguistics, deals with studying how each language and therefore the societies or societies with common values perceive the world and reflect it through the language they use, what qualities of entities and concepts surrounding them they distinguish, how they describe feelings and thoughts of a human being and their value judgments. This paper studies analogies and idioms that are formed by means of preposition “gibi” in the Turkish language and “sıyaktuu” with the suffix –Day in the Kyrgyz language, which are examined in the context of comparative cultural linguistics. Thus, the differences and/or similarities between the perception of external world between the two societies are revealed.

The Relationship

The use of computer technology is increasingly becoming a way of life for professional salespeople.  Given the increased use of technology in virtually aspects of sales, it would seem natural to reconcile both the uses of, and attitudes toward, computers among professional salespeople with traditionally emphasized sales constructs such as adaptability and customer orientation.  The results of such an analysis would have implications for both academic sales research as well as sales managers and trainers who would benefit from an investigation into a propensity to accept computer technology and the ability to engage in significant sales activities that represent the human dimension.  The current study addresses this issue by assessing the relationships between salespersons’ attitudes toward computer technology, adaptability, and customer orientation.  The findings generally indicate a positive predisposition toward computer usage and a significant positive relationship between those attitudes and both adaptability and customer orientation among a sample of professional salespeople.

Purpose This study aims to determine the impact of social media usage on university student’s academic performance in Ghana. Design/methodology/approach A quantitative research method was used for the study. With the aid of a simple random sampling technique, quantitative data were obtained from 373 out of 400 respondents representing 93 per cent of volunteered participants. Data collected was analysed using structural equation modelling to establish the relationship among social media information, social media entertainment, social media innovation, social media knowledge generation and student performance. Findings The findings of this study indicate that social media information, social media innovation and social media entertainment all had a significant positive influence on social media knowledge generation, which has wide learning and knowledge management implications. Also, the study indicated that information computer technology knowledge moderates the relationship between social media and student performance. Research limitations/implications The sample taken was mainly cross-sectional in nature rendering the inference of causal relationships between the variables impossible. Future researchers should adopt a longitudinal research design to examine causality. Finally, the study was limited to only university students in Accra, Ghana. Future research can extend to a bigger student population and to other West African and African countries. Practical implications This paper will serve as a profitable source of information for managers and researchers who may embark on future research on social media and academic performance. The findings that social media information, innovation and entertainment can likewise enhance social media knowledge generation can help managers and university teachers to use the vehicle of innovation and entertainment to communicate knowledge. Social implications The findings of this study will help policymakers in education and other industries that engage the youth to realise the important factors that can make them get the best in the social media space. Originality/value Social media usage in academic performance is increasingly prevalent. However, little is known about how social media knowledge generation mediates between social media usage and academic performance and, furthermore, whether the information computer technology knowledge level of students moderates the relationship between social media knowledge generation and academic performance of university students in sub-Saharan Africa, particularly Ghana. Theoretically, the findings of this study provide clear research evidence to guide various investigations that can be done on the relationships of the variables under social media usage, knowledge generation and university student performance, which advances the diffusion of new knowledge.

The Relationship

To study the cognitive process of the human brain in dealing with philosophical issues, for the first time, from the perspective of scientific experiments, the issue of “relationship” in philosophy was verified. A set of algorithms combining physiology analysis and computer technology linearity and a nonlinear manifold learning algorithm were proposed. Two groups of auditory cognitive experiments were performed, and the concept expected effect was defined as the symbol of conceptual intervention. From the perspective of time, whether the concept was involved after the sensation arises was explored. EEG (electroencephalogram) physiology was used to analyze the data. The results showed that the concept induced a positive shift of the waveform after intervention. It has little effect on the early components, but it has a significant effect on the composition of the sensory components. Waveform changes before and after conceptual intervention have significant main effects. Perceptual production does not involve conceptual intervention, which verifies, in time, that “the relationship” exists.
