Fuller's sociological social epistemology can prompt deep philosophical analyses of the conditions for knowledge that themselves bear on what should count as knowledge. That is, it can be a vital prelude to developing an interdisciplinary investigation into educational issues. This paper looks at the three features that form an integral part of Fuller's social epistemology, which is partly elucidatory and partly critical: naturalistic, normative, and organizational aspects. It goes on to explore whether and to what extent Fuller's criticism of an "always already" thesis in philosophy and his idea of "knowledge management" afford an understanding of human knowledge in particular and human development in general. This paper concludes with an observation that Fuller's social epistemology is flawed in some respects but nonetheless is of relevance to the philosophical study of education.展开更多

Ready-to-drink beverage as a vehicle for fortification is easy to administer, more consistent and least obstructive, because it can be consumed without further processing/cooking. This study aimed to evaluate the effectiveness of fortified beverage on the improving of iron status and school performance test of schoolchildren. About 5,000 schoolchildren aged 6-12 years old from 19 schools in Quirino province, Philippines were invited to participate in the study. Samples of 4,875 children with parental consent were screened for hemoglobin and serum ferritin levels. About 4,495 children had complete participation in the school performance test, which were developed and administered by school supervisors. Children were fed 200 mL ready-to-drink juice fortified with iron, zinc, lysine, vitamins A and C for 120 d. The beverage was delivered through the baseline. At end of the intervention, only 1,050 children had complete data set and the anemia rate reduced from 100% to 60%. Iron deficiency has increased insignificantly from 3.6% to 4.5%. Mean percentage of test scores increased significantly between base and end of the study: English (40% to 60%), math (35% to 58%) and science (32% to 58%). In conclusion, consumption of 200 mL fortified juice drink had contributed to the reduction of anemia and increased tests scores of children.展开更多

However, learning another language does not occur identically among all students. Some students learn a language, even their own mother tongue earlier but some others may need to spend more time acquiring a language. Seeking out for the probable reasons for such a difference, the current study following the constructivist approach to language learning and bearing in mind the role of society and human communities in language learning, was concluded to investigate the probable impact(s) of some social variables (social status, attitudinal and motivational status of learners) on language learning outcomes of Iranian adult learners assessed through a standardized English proficiency test. The findings have revealed that the social milieu in which learners live may play a decisive role as far as learning opportunities, input and resources are concerned.展开更多

The interest in this issue arises for various reasons, from the growing economic significance of the sector at a national level, measurable in terms of production value and the number of operators involved, to the spread of outsourcing policies, liberalization and privatization, and the use of the standard cost to establish the level of funding. In the field of public utilities, until a few years ago, the concept of control was intended only in a "bureaucratic" sense as the capacity to fulfill the formal obligations linked to the strong regulatory context, ignoring aspects that have become fundamental today, such as economy, efficiency, and effectiveness of management. The approach used is deductive and the study ends with the presentation of the possible implications of the use of standard cost and the presentation of an application hypothesis of a balanced scorecard (BSC) for local public transport (LPT).展开更多

Not much research is done to examine lower intermediate English as a Foreign Language (EFL) learners' performance on the reading section of the First Certificate of English exam (FCER) in the post strategy instruction period. The results indicate that learners vary not only in terms of their performance on the FCER, hut also on the employed metacognitive strategy. Furthermore, metacognitive strategies are the only predictors that positively predict learners' performance in the FCER.展开更多

These entrepreneurs constitute a majority of businesses and employ a significant part of the population, thus, they are vital for the economy of Hong Kong. This research looks into and studies this phenomenon to evaluate the various components of the success of these entrepreneurs and to draw conclusions that will benefit the educators, the legislators as well as the new entrants who wish to become entrepreneurs. By interviewing Hong Kong entrepreneurs, it has been found that the main source of entrepreneurial success in Hong Kong is of very complex origin. The Hong Kong's entrepreneurs seem to succeed, when they are able to blend the best qualities of the East and the West. Based on the research outcomes, the perceptions, achievements, strategies, and traits (PAST) model has been developed to assist Hong Kong entrepreneurs in the future.展开更多

In a flash-back narration, the novel tells us the legendary experience of Nyasanu in Africa before he becomes a slave in the south of America, portrays a well-rounded and authentic Black male character, and constructs a model of masculinity of great value for reference. The model of masculinity demonstrated by Nyasanu is no longer limited by the rigid and unitary stipulations of traditional gender concept. It is a model which integrates tenderness into toughness, combines physical power or military prowess with mental power or wisdom, and most importantly, a model that stresses men's agency and authenticity. At the same time, by the resentment of war and cherishement of life, this model of masculinity exhibits considerable ethical dimension and humanitarianism. It can be said that the model of masculinity inscribed in The Dahornean is of much enlightening importance for contemporary people to reflect upon the patriarchal culture and prevalent gender notions such as gender role concept. As for people's pursueing and constructing their ideal masculinity, the model of masculinity embodied in The Dahomean can be an important model for reference.展开更多

Now, in addition to the ordinary full-time higher education, these two education systems are important for the education system in China, and also are important ways for people to learn knowledge and get a diploma. However, a great number of students raise many questions about the difference between the two systems, and feel highly confused about choosing adult higher education or higher education' s self-study exam currently. In this paper, the similarities and differences between adult higher education and higher education ' s self-study exam are discussed, so that a good choice is easily made by students before one of them is applied.展开更多

The MINS and magnetometers are commonly the component parts of the attitude and heading reference systems (AHRS), which provide pitch and roll angles relative to the earth gravity vector, and heading angle relative to the north. However, the performance of sen- sors with low cost AHRS is not so good. The gyros are not sensitive enough to observe the earth an- gular velocity, so the traditional technique like alignment algorithm is invalid. The measurements of gyros become useless to determine the initial attitude matrix from navigation frame to body frame. The alignment algorithm is computed by the accelerometers and magnetometers. The process is es- tablished as an optimization problem of finding the maximum eigenvector. Meanwhile the sensitive analysis with respect to the biases of accelerometers is proposed. Then the recursive least squares al- gorithm (RLSA) is introduced. The comparison between the proposed method and RLSA is provid- ed. The results demonstrate its accuracy favorably and verify the feasibility of the proposed algo- rithm.展开更多

Prediction equations of the European Community for Steel and Coal (ECSC), other equations for overseas Chinese or for Caucasians were also selected. The regression coefficients of forced vital capacity (FVC), forced expiratory volume in one second (FEV 1), FEV 1/FVC, total lung capacity (TLC) and residual volume (RV) were summarized. Results ECSC predictions were closer to the Chinese ones than other selected equations. Comparison with ECSC predictions showed that on average the values for FVC, FEV 1 were 5.3% smaller in Chinese males and 3.3% smaller in Chinese females, with the maximal differences in south China and the minimal differences in North China. RV and TLC in Chinese were lower than in Caucasians (males 4.8%, 5.5%, respectively; females 8.7% and 6.0%, respectively). Conversion factors were given for adjusting ECSC equations to fit Chinese. Conclusions For predicting values of pulmonary function in Chinese, we suggest to use the equations reported here. Alternatively, ECSC regression equations may be used with appropriate conversion factors.展开更多
