An integrated DBP for streams with (<Emphasis Type="Italic">m,k</Emphasis>)-firm real-time guarantee
(m,k)-firm real-time or weakly hard real-time (WHRT) guarantee is becoming attractive as it closes the gap between hard and soft
(or probabilistic) real-time guarantee, and enables finer granularity of real-time QoS through adjustingm andk. For multiple streams with (m, k)-firm constraint sharing a single server, an, on-line priority assignment policy based on the most recentk-length history of each stream called distance based priority (DBP) has been proposed to assign priority. In case of priority
equality among these head-of-queue instances, Earliest Deadline First (EDF) is used. Under the context of WHRT schedule theory,
DBP is the most popular, gets much attention and has many applications due to its straightforward priority assignment policy
and easy implementation. However, DBP combined with EDF cannot always provide good performance, mainly because the initial,
DBP does not underline the rich information on deadline met/missed distribution, specially streams in various failure states
which will travel different distances to restore success states. Considering how to effectively restore the success state
of each individual stream from a failure state, an integrated DBP utilizing deadline met/missed distribution is proposed in
this paper. Simulation results validated the performance improvement of this proposal.

The long-arm and short-arm genes of fibroin light chain (L-chain) of silkworm,Bombyx Mori L., and the gene of human acidic fibroblast growth factor were cloned respectively and subsequently inserted into a transfer
vector pVL 1392 used as a tool to target the L-chain region of the silkworm genome. Genomic DNA from their offsprings was
extracted and the expected targeting was detected using polymerase chain reaction and DNA sequencing, as well as protein analysis.
The results showed that positive events occurred and that the FGF gene was integrated into the L-chain locus through homologous
recombination.

Over the past 20 years, relational theories of leadership have gained increased traction in the global discourse in educational leadership. This is observable in the increased frequency with which scholars have begun to construct leadership within the sociocultural and institutional systems of different societies. This study addressed the question, “How is effective school leadership constructed in the multi-faceted education context of modern day Vietnam?” We employed a multi-site case study research design to collect qualitative data from several stakeholder groups in three Vietnamese schools. Analysis centered on describing and synthesizing how principal leadership was constructed in these settings. This study “contextualized school leadership” by describing how leadership themes of managing relationships, preserving harmony, and teacher empowerment were shaped by institutional, political and socio-cultural forces in Vietnamese society. The findings support the importance of contextualizing leadership in order to understand differences in how “effective school leadership” is constructed and understood across different societies. 相似文献

The study inquired into the effect of research-based video-cases on pre-service teachers conceptualizing their understanding
of contemporary mathematics teaching. The 43 participants enrolled in a Mathematics Method Course viewed and discussed 5 video-cases
of primary teachers teaching. Journal entries, lesson plans, and microteaching observations were collected as data on which
the following assertions were based. Pre-service teachers' responses to the 5 videos were more concerned with pedagogical
content knowledge than mathematical content and students' learning. They refocused and deepened their awareness of students'
learning and questioning skills through discussing the videos. The video-cases improved their construction of pedagogical
representation and their ability to identify a problematic situation with multiple perspectives. These effects appeared to
be influenced by the scaffold of three factors: vicarious experience to complement personal experience, watching and discussing
video-cases enriched by the developers, and journal writing to foster deeper reflections. 相似文献

Mechanical properties and low cycle fatigue are two factors that must be considered in developing new type steel for shock
absorption. Process capability and process control are significant factors in achieving the purpose of research and development
programs. Often-used evaluation methods failed to measure process yield and process centering; so this paper uses Taguchi
loss function as basis to establish an evaluation method and the steps for assessing the quality of mechanical properties
and process control of an iron and steel manufacturer. The establishment of this method can serve the research and development
and manufacturing industry and lay a foundation in enhancing its process control ability to select better manufacturing processes
that are more reliable than decision making by using the other commonly used methods. 相似文献

We study Spanish savings banks from the point of view of their efficiency, transparency in the disclosure of financial information through the net, and the provision of electronic banking services. Performance indicators are developed using data envelopment analysis and the tools of multivariate statistical analysis. The choice of indicators is framed within the theory of intangible assets. An attempt is made rank savings banks according to their level of achievement in each indicator. Savings banks are shown to be classified into four groups according to the level of achievement in the indicators of transparency and e-service. The relationship between efficiency and profitability is also discussed. 相似文献
