This study investigates the relationship between Principal Change Leadership Competencies, Teacher Change Beliefs and Teacher Attitudes toward Change. A total of 936 teachers from 47 High Performing Secondary Schools in Malaysia completed the survey. Structural equation modelling was applied to test the models. Firstly, the results showed that Principal Change Leadership Competencies was significantly related to Teacher Change Beliefs and implied that if school principals equipped themselves with sufficient Principal Change Leadership Competencies, Teacher Change Beliefs can certainly be enhanced. Secondly, Teacher Change Beliefs was significantly related to Teacher Attitudes toward Change whereby the stronger the Teacher Change Beliefs, the greater the enhancement of Teacher Attitudes toward Change. Thirdly, Teacher Change Beliefs was indeed a total mediator in the relationship of Principal Change Leadership Competencies and Teacher Attitudes toward Change. Put simply, via Teacher Change Beliefs, the impact of Principal Change Leadership Competencies on Teacher Attitudes toward Change was relatively strong as Teacher Change Beliefs greatly facilitated the influence of Principal Change Leadership Competencies on Teacher Attitudes toward Change. Thus, in-depth enhancing Teacher Change Beliefs is one of the effective ways to increase the likelihood of teachers to embrace change. Fourthly, Principal Change Leadership Competencies was more influential than teachers’ self-influence in enhancing Teacher Attitudes toward Change. Therefore, concerted effort must be given to prioritize the continuous development of principal change leadership in effective change management. The study encourages a fresh look at change leadership development and ultimately alters the traditional approach of school principals in managing change. 相似文献

This study employs content analysis to examine how the New York Times and St. Louis Post-Dispatch framed “Black Lives Matter” protests in the aftermath of the shooting of unarmed black teenager Michael Brown. The researchers examine all New York Times and St. Louis Post-Dispatch articles dealing centrally with the Michel Brown protests during three separate time periods corresponding to heavy protest activity. The coding scheme measured dominant frame direction, article length, sourcing, and mention of protester crimes. Contrary to expectations, the papers provided overwhelmingly sympathetic coverage of “Black Lives Matter” protests. In describing the protests, both newspapers were much more likely to employ a “positive” frame suggesting peacefulness and order than a “negative” frame suggesting lawlessness and deviance. Neither newspaper over-emphasized protester-perpetrated crimes, with both papers making relatively infrequent mention of looting, arson, assault, and gunfire, respectively. Importantly, both newspapers directly quoted protesters much more often than they quoted police officers and other government officials. 相似文献

This paper studies stochastic impulsive systems with time delay, where the impulse times are state-dependent. Using Itô calculus, we develop the essential foundation of the theory of the mentioned system. In particular, we establish results on local and global existence, forward continuation, and uniqueness of adapted solutions. 相似文献

This research examines how Malaysian managers and employees interpret and embody leader–member relationships differentiation. To analyze this question, we conducted a thematic analysis of top management, middle management and supporting dialogue group discussions. Results showed that leader–member relationships differentiation is a symbol that is essential for the creation and sustenance of leader’s conceptual skills, communication openness, respect, trust, and age differentiation. These findings validate our proposition of leader–member relationships differentiation in Malaysian workplace and empirical support for the central roles of communication exchange processes in workgroups. 相似文献

Determination of amyloid β (Aβ) isoforms and in particular the proportion of the Aβ 1-42 isoform in cerebrospinal fluid (CSF) of patients suspected of Alzheimer’s disease might help in early diagnosis and treatment of that illness. Due to the low concentration of Aβ peptides in biological fluids, a preconcentration step prior to the detection step is often necessary. This study utilized on-chip immunoprecipitation, known as micro-immunoprecipitation (μIP). The technique uses an immunosorbent (IS) consisting of magnetic beads coated with specific anti-Aβ antibodies organized into an affinity microcolumn by a magnetic field. Our goal was to thoroughly describe the critical steps in developing the IS, such as selecting the proper beads and anti-Aβ antibodies, as well as optimizing the immobilization technique and μIP protocol. The latter includes selecting optimal elution conditions. Furthermore, we demonstrate the efficiency of anti-Aβ IS for μIP and specific capture of 5 Aβ peptides under optimized conditions using various subsequent analytical methods, including matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), capillary electrophoresis, microchip electrophoresis, and immunoblotting. Synthetic Aβ peptides samples prepared in buffer and spiked in human CSF were analyzed. Finally, on-chip immunoprecipitation of Aβ peptides in human CSF sample was performed. 相似文献

ABSTRACTSubject Librarians play an important role in an academic library, a role which it is crucial to study. There have been many published studies that have highlighted the lack of evidence on the competencies of Subject Librarians. This paper discusses the challenges faced by the Subject Librarians of the Universiti Putra Malaysia Library. The aim was to gather information from published documents regarding the experiences and practices carried out in efforts to increase the competencies of Subject Librarians. The outcomes from this conceptual paper serve as an important instructional tool for the training and development of Subject Librarians. The results might also provide guidance for the implementation of a similar program or relevant problem-solving plans for other libraries in the region. 相似文献

This paper explores the interrelationships of the key influences on student satisfaction via multivariate analysis from three groups of university students in two popular private universities in Malaysia. The correlation coefficient and structural model indicated that student satisfaction is influenced not only by academic quality, but also by the university core services, information technology services, and skill building. These dimensions are linked to one another. The strong interrelationships between these dimensions are indicative that holistic approach needs to be adopted rather than dealing with each dimension in isolation in creating a valued education. Significant performance gaps of key influences indicated that the satisfaction levels are below students’ expectation despite the satisfaction scores being above average. Academic assessment, teaching quality, and IT are areas where a university management needs to prioritize resources in order to increase student satisfaction. Students who perceived higher value are more likely to have higher repurchase intention. 相似文献

In this paper, we study characteristics of polymers (methylcellulose, hypromellose ((hydroxypropyl)methyl cellulose), poly(vinylpyrrolidone), and poly(vinyl alcohol)) with different chemical structures for microchip electrophoresis of non-denatured protein samples in a plastic microchip made of poly(methyl methacrylate) (PMMA). Coating efficiency of these polymers for controlling protein adsorption onto the channel surface of the plastic microchip, wettability of the PMMA surface, and electroosmotic flow in the PMMA microchannels in the presence of these polymers were compared. Also relative electrophoretic mobility of protein samples in solutions of these polymers was studied. We showed that when using low polymer concentrations (lower than the polymer entanglement point) where the sieving effect is substantially negligible, the interaction of the samples with the polymer affected the electrophoretic mobility of the samples. This effect can be used for achieving better resolution in microchip electrophoresis of protein samples. 相似文献
