Entry and competitive dynamics in the mobile telecommunications market

We propose an extension of the Gans-Stern [Gans, J.S., Stern, S., 2003. The product market and the market for “ideas”: commercialization strategies for technology entrepreneurs. Research Policy 32 (2), 333-350] framework that includes entry by existing firms. An incumbent firm possessing complementary assets and strong appropriability is in a formidable position [Teece, D.J., 1986. Profiting from technological innovation: implications for integration, collaboration, licensing, and public policy. Research Policy 15 (6), 285-305]. However, a de alio entrant can leverage complementary assets to enter along a new technological trajectory, and then develop appropriability. We illustrate how several mobile telecommunications firms (Ericsson, Nokia and Samsung) pursued this strategy to catch up with the market leader (Motorola). We also identify several shortcomings in Motorola's approach: it was too inward-looking in developing technologies, but ironically not inward-looking enough in exploiting its most valuable patents.     

A new type of transitional filter based on summation of polynomials

A new transitional filter based on the sum of filter polynomials is proposed and discussed. It shall be shown that the approach allows for greater flexibility in adjusting passband and stopband gain shapes. The sensitivity of the filter transfer function is analyzed and related to the approximation problem. Some new modified classical filters are also derived including maximally flat (Butterworth) and equiripple (Chebyshev) types. Several examples of combining Butterworth, Chebyshev and sync-tuned filters are presented and compared to those obtained using the conventional product method. The new transitional filter provides an alternative to other forms and provides a means for isolating the effects of non-uniformly distributed pole angles.     

Implementing Performance Indicators of early learning and teaching: A Chinese study

This study investigated how a set of newly developed indicators of early learning and teaching by the government, which was based on western ideology of child learning, was implemented in a Chinese context like Hong Kong. Twelve early childhood settings of 5747 children and 284 staff volunteered to implement the indicators within two years and the processes were observed and analysed. A multi‐method, multi‐source data collection strategy was used to document the self‐evaluation and improvement process. All the participating settings went through the five stages of the evaluation cycle: understanding the Performance Indicators, assessing learning and teaching, formulating an action plan for improvement, implementing the action plan, and reflection. The results indicated that: (1) implementing a quality assurance cycle took time, resources and commitment; (2) the implementation helped to enhance practitioners’ professionalism; and (3) teacher professionalism was the key to the success of this quality assurance mechanism. The socio‐contextual factors and the educational implications of these findings are discussed.     

Parameters selection in gene selection using Gaussian kernel support vector machines by genetic algorithm

INTRODUCTION Recent techniques based on oligonucleotide or cDNA microarrays allow the expression level of thousands of genes to be monitored in parallel (Golub et al., 1999). A critically important factor for cancer diagnosis and treatment is the reliable prediction of tumor progression. A remarkable advance for mo- lecular biology and for cancer research is cDNA mi- croarray technology. cDNA microarray datasets havea high dimensionality corresponding to the large number of genes monit…     

Comparing state hegemonies: Chinese universities in postwar Singapore and Hong Kong

After World War II, Chinese residents of Singapore demanded the establishment of local Chinese universities. The ruling regime, however, which was under the shadow of the neighboring Malay‐dominated Malay Peninsula, was forced to suppress the development of such schools. In Hong Kong, the British needed to install a Chinese university to counter Beijing’s and Taiwan’s campaigns for recruiting students from the colony. As Hong Kong was a monoracial Chinese society, the government, not having to worry about the reaction of other indigenous groups, met this challenge by founding a fully recognized Chinese university. This research demonstrates that under diverse backgrounds of racial politics, state authorities have unequal latitudes to accommodate the educational institutions of subordinated racial groups. It also reveals that state education policies in small and dependent settings, unlike those in big and sovereign nations, are more susceptible to pressures from external powers and influences from the metropolis. These findings urge scholars to pay more attention to the factor of race and use comparative methods when employing the theories of state and hegemony to investigate education and power.     

To click or not to click: Effectiveness of rating classroom behaviors on academic achievement with tablets

Due to the time constraint and lack of concise contextualized classroom behavior indicators, current typical primary school classroom behavior management practices are ad-hoc and lack historical data support. To circumvent these problems, we designed a tablet-based classroom behavior management system (CBMS) for a primary school setting. The CBMS aids teachers in establishing concise and consistent behavioral expectations based on teaching experience and expertise, thus allowing them to conveniently provide timely feedback on pupils’ performance and log ratings on a daily basis. We conducted a 1.5 years field study in a primary school Chinese course in East China, in which 124 pupils in the first grade and four Chinese teachers participated. The analysis of recorded data indicates that teachers’ daily behavioral ratings are positively correlated with their pupils’ academic achievements. The behavior rating strategy and indicators in CBMS can act as a substitute in promoting pupil's academic achievements. Our proposed system shows the feasibility and potential of handheld computer-based assessment strategy in implementing cost-effective classroom organization practices for low grade-level primary school pupils.     

The learning community narrative: An essential first step in creating and sustaining program identity

As individuals, we often come to understand our identity through our stories. Emilly Borthwick‐Wong and Janna Jones argue that the same is true for educational programs; a successful, long‐term educational program must be able to communicate its purpose and importance in an easily told narrative.     

Chinese and Taiwanese International College Students' Participation in Social Organizations: Implications for College Counseling Professionals

This qualitative focus group study explored the meaning of Chinese and Taiwanese international students' lived experiences in social organizations. Participants were 9 Chinese and Taiwanese international college students in a midwestern U.S. university. The analyses uncovered 7 themes: social support, recreation, emotional support, practical benefits, contributions to the organizations, commitment toward organizations, and stressors associated with participation. Implications of the findings for college counseling professionals are discussed.     

Is there creativity in design? From a perspective of school design and technology in Hong Kong

As creativity is likely to become a crucial aspect of living in the future, it is important for educators to teach students to think creatively when solving constantly evolving and increasingly complex problems. Supported by the idea that creativity can be taught and learnt, elements of creativity are now embedded in secondary school education. Among all school subjects, design and technology (D&T) is one of the best examples for fostering and cultivating students?? creativity, as the subject offers creative activities that enable students to realize their ideas in the context of the real world. This paper analyzes the creative elements in the D&T curriculum in Hong Kong as seen in the exemplar projects on the Education Bureau website. Some problems and difficulties encountered in fostering creativity in the context of Hong Kong are identified, based on the current teaching environment. The paper also draws attention to East Asian beliefs and implicit theories, which greatly influence teachers?? underlying assumptions about learning and teaching, and at the same time notes that these beliefs may be detrimental to the development of creativity among students. The paper then identifies the problems and inadequacies in fostering creativity in design at the secondary school level and expects to raise awareness of the importance of creativity in D&T.     

The capstone experience: student and academic perspectives

A principal consideration in recent cross-sector educational reforms in Hong Kong is ensuring that undergraduate programmes prepare students for the future workplace, a factor that has made the capstone a central feature of the new four-year curriculum. This paper discusses a study that explored the final-year student experience based on a final-year project (FYP). Both recent graduate and final-year student feedbacks reveal some uncertainty and a lack of confidence over successful transition that graduates attribute to an overtly research focus in the current design of FYPs. Inviting comment from senior academics allows a fuller picture of the rationale behind, and administrative considerations in, conducting a capstone experience. This formative study highlights specific features in designing a capstone experience and the need for academic engagement in order to support the desired outcome of graduate employability.
