This study investigates the impact of transformational leadership as idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration on teachers’ commitment towards organization, teaching profession, and students’ learning. A quantitative survey method was applied, and four broadly hypothesized relationships were tested with a sample of 1,014 trained non-graduate and graduate teachers serving in twenty-seven secondary schools in Sarawak, Malaysia. The results indicate a moderate level of teachers’ commitment and a low level of transformational leadership qualities among the respondents. This study found that inspirational motivation, individualized consideration, and intellectual stimulation were the factors contributing towards teachers’ commitment to teaching profession, and there was no dominant factor influencing commitment to students’ learning. Moreover, it was discovered that inspirational motivation was a factor to teachers’ efficacy and teaching experience. Besides, teachers’ efficacy and teaching experience were predictors to teachers’ commitment to organization, teaching profession, and students’ learning, respectively. These findings revealed that there was a significant relationship between transformational leadership and teachers’ commitment to organization and teaching profession, but not students’ learning. The results of this study indicate the necessity for leadership development of school leaders so that they could systematically acquire and internalize the effective transformational leadership qualities that are crucial in changing teachers’ attitude and improving their commitment towards their profession. 相似文献

In this essay, Mohammed Albakry discusses the notion of accommodating cultural differences in translation and the need to respect these differences without compromising or emphasizing them. First, Albakry reflects on translation as an act of interpretation in light of Terence's famous saying “nothing human can be foreign to me.” Second, he comments on the place of drama in translation and translation studies in order to contextualize his project — translating a number of critically acclaimed contemporary Egyptian plays. He then reviews and critiques the binary model of foreignization/domestication, drawing on some concrete examples of the cultural challenges of translating Arabic drama for the American stage. Albakry concludes by conceptualizing an alternative translational space of dialogical encounters between the human/familiar and the foreign in translation, and by considering the relevance of the Terentian maxim to the negotiation of maintaining sameness while preserving difference. 相似文献

The purpose of this study is to examine the manner in which the features of a constructivist learning environment, and the mechanisms at its base, are expressed in junior high school students’ conceptions. Our research is based on an integration of quantitative and qualitative approaches, deigned to provide a wider ranging and deeper understanding. Eight hundred and forty eighth- and ninth-grade students from over 15 schools participated in the study. Of the 840 students who completed the questionnaire, the explanations of 200 well-written questionnaires were further analyzed qualitatively. The findings of the study are presented in terms of the four scales employed in the CLES, namely the autonomy scale, the prior knowledge scale, the negotiation scale, and the student-centeredness scale. The quantitative results achieved here concur with parallel studies conducted around the world. The findings indicate that a considerable portion of the students perceive their learning environment as a constructivist one and report positive attitudes toward the way they are being taught. In terms of the qualitative results, however, it appears that in some cases, the students’ explanations reveal that in fact, and contrary to the bare quantitative results, some students do not perceive their learning environment as being constructivist. This raises the question of whether the fact that students recognize the factors associated with constructivist teaching is indeed an indication that such teaching exists in practice. This finding emphasizes the importance of combining qualitative and quantitative methods for arriving at a balanced view of classroom occurrences. 相似文献

The present work demonstrates the use of a dielectrophoretic lab-on-a-chip device in effectively separating different cancer cells of epithelial origin for application in circulating tumor cell (CTC) identification. This study uses dielectrophoresis (DEP) to distinguish and separate MCF-7 human breast cancer cells from HCT-116 colorectal cancer cells. The DEP responses for each cell type were measured against AC electrical frequency changes in solutions of varying conductivities. Increasing the conductivity of the suspension directly correlated with an increasing frequency value for the first cross-over (no DEP force) point in the DEP spectra. Differences in the cross-over frequency for each cell type were leveraged to determine a frequency at which the two types of cell could be separated through DEP forces. Under a particular medium conductivity, different types of cells could have different DEP behaviors in a very narrow AC frequency band, demonstrating a high specificity of DEP. Using a microfluidic DEP sorter with optically transparent electrodes, MCF-7 and HCT-116 cells were successfully separated from each other under a 3.2 MHz frequency in a 0.1X PBS solution. Further experiments were conducted to characterize the separation efficiency (enrichment factor) by changing experimental parameters (AC frequency, voltage, and flow rate). This work has shown the high specificity of the described DEP cell sorter for distinguishing cells with similar characteristics for potential diagnostic applications through CTC enrichment. 相似文献

ABSTRACT This paper examines the emergence of a news ecosystem, focusing on Hespress, Morocco’s first, largest, and most popular news website and its current economic success. My analysis investigates Hespress’s emergence and growth into a significant source for news content, reaching an unprecedented number of readers in Morocco and abroad. This paper argues that the success of Hespress’s business model is grounded in a particularly well-developed understanding of social media, the changing habits of digital readers, and a strategic combination of investigative reporting and curated user-generated content. My findings, then, show how Hespress used a strategy that can serve as a sustainable revenue model which was diversified to include other sources of revenue such as e-commerce, branded events, and native advertising, combined with distribution strategies that rely heavily on social and other digital platforms. 相似文献

This paper presents our work towards developing a new speech corpus for Modern Standard Arabic (MSA), which can be used for implementing and evaluating Arabic speaker-independent, large vocabulary, automatic, and continuous speech recognition systems. The speech corpus was recorded by 40 (20 male and 20 female) Arabic native speakers from 11 countries representing three major regions (Levant, Gulf, and Africa). Three development phases were conducted based on the size of training data, Gaussian mixture distributions, and tied states (senones). Based on our third development phase using 11 hours of training speech data, the acoustic model is composed of 16 Gaussian mixture distributions and the state distributions tied to 300 senones. Using three different data sets, the third development phase obtained 94.32% and 8.10% average word recognition correctness rate and average Word Error Rate (WER), respectively, for same speakers with different sentences (testing sentences). For different speakers with same sentences (training sentences), this work obtained 98.10% and 2.67% average word recognition correctness rate and average WER, respectively, whereas for different speakers with different sentences (testing sentences) this work obtained 93.73% and 8.75% average word recognition correctness rate and average WER, respectively. 相似文献

Managing personal information such as to-dos and contacts has become our daily routines, consuming more time than needed. Existing PIM tools require extensive involvement of human users. This becomes a problem in using mobile devices due to their physical constraints. To address the limitations of traditional PIM tools, we propose a model of mobile PIM agent (PIMA) that aims to improve PIM on mobile devices through natural language interface and application integration. We conducted a user study to evaluate PIMA empirically with prototype systems. The results show that mobile PIMA improved perceived usefulness, ease-of-use, and efficiency of PIM on mobile devices, which in turn accounted for positive attitude and intention to use the system. The findings of this study provide suggestions for designing and developing PIM applications on mobile devices. 相似文献

This paper proposes a fuzzy model predictive control (FMPC) combined with the modified Smith predictor for networked control systems (NCSs). The network delays and data dropouts are problems, which greatly reduce the controller performance. For the proposed controller, the model of the controlled system is identified on-line using the Takagi – Sugeno (T-S) fuzzy models based on the Lyapunov function. There are two internal loops in the proposed structure. The first is the loop around the FMPC, which predicts the future outputs. The other is the loop around the plant to give the error between the system model and the actual plant. The proposed controller is designed for controlling a DC servo system through a wireless network to improve the system response. The practical results based on MATLAB/SIMULINK are established. The practical results are indicated that the proposed controller is able to respond the networked time delay and data dropouts compared to other controllers. 相似文献

Following the events of 9/11, many misconceptions entered the policy-making platform with regard to the need for education reforms in the Muslim world. Based upon Western cultural and societal norms and increased scepticism of the role of religion in violence, these assumptions have triggered a strong wave of calls for a top-down approach to reform formal state schools in predominantly Muslim countries, These calls often meet with resistance at national and community levels. This article seeks to examine these misconceptions and investigate why educational reform efforts through top-down frameworks which are especially motivated by countering violent extremism or terrorism have had only limited success. Many major international intergovernmental organisations, non-governmental organisations and governments have invested time and effort into education measures aiming to build peace and coexistence in Muslim countries, but they have been unable to build a relationship of trust with community leaders and school authorities. The authors argue that the main reason for defiance is reformers’ failure to closely examine the cultural context of their chosen setting and work with existing tools and local institutions. Illustrating their point with a case study of an intervention carried out in informal Qur’anic schools in Niger, West Africa, the authors offer an alternative method which fosters changes from within. They argue that this model has a better chance of sustainability and could thus be used as the basis for future interventions. 相似文献

This study was conducted to investigate the diagnostic performance characteristics of prostate specific antigen (PSA) by comparing
serum PSA value with histological findings in patients suspevted of having prostate cancer in Aminu Kano Teaching Hospital.
Nigeria. Clinical and Laboratory records were examined and collated for serum PSA values, together with histological findings
of biopsy specimen, clinical diagnosis, age of patients, and mode of presentation. The serum PSA values were determined by
ELECSYS 1010 autoanalysers Roche, Germany based on electrochemiluminescence immunoassay technique. The results show that serum
PSA values increase with age in the assymptomatic non-cancer patients who came for medical check up but were within normal
limit. In prostatic disease conditions PSA values were raised in benign prostatic hyperplasia 35.957± 4.0315ng/ml, in undifferentiated
carcinoma 56.22±4.295ng/ml and adenocarcinoma >100ng/ml as compared to the normal range (0–4ng/ml). These cases were confirmed
by histological diagnosis. It is concluded that PSA evaluations is a sensitive marker for prostate cancer but because of various
other conditions that affect serum PSA concentration, other methods of investigations such as Digital Rectal examination,
Trans Urethral Ultra-Sonography and histological examination should be combined to confirm diagnosis. Prognosis of patients
will be better if early diagnosis is made. 相似文献
