Sun, Ran and Du, Ping
- Abstract
Based on the baseline data of the China Education Panel Survey, this paper explored the relationship between teacher training and academic performance in urban and rural samples respectively and the impact of teacher training on the urban-rural gap of students' academic performance. The results showed that: firstly, there was a significant urban-rural gap in academic performance, and the gap in high quantiles and language subjects were even larger. Secondly, the results of unconditional quantile regression showed that teacher training could improve the performance of urban students with different academic levels and rural students with intermediate or above academic levels, but it cannot improve the performance of rural students with lower academic levels. In addition, the overall effect of teacher training in urban areas is significantly higher than that in rural areas. Thirdly, different quantiles of Oaxaca-Blinder decomposition found that the endowment effect and the coefficient effect of teacher training were the important causes of the urban-rural performance gap, but the relative sizes of the two were different according to the different grades and different quantiles of performance distribution. Therefore, to increase the training opportunities and improve the training quality of rural teachers as well as enhance the resource conversion rate of rural students are of great practical significance for narrowing the urban-rural performance gap.

3. Languaging Dynamics in Interactive Lecturing: Exploring an Embodied Approach to Deep Learning in L2 Higher Education Contexts

Shi, Dan, Irwin, Derek, and Du, Ping
- Abstract
The present study aims to explore an embodied approach to students' deep learning; specifically, how deep learning is interactively achieved through teachers' languaging dynamics and multimodal representations in interactive lecturing in L2 higher education (HE) contexts. The purpose is to understand how an instructor's embodied and multimodal pedagogical practices of interactive teaching facilitate students' active classroom engagement in lecture sessions that are often considered a form of passive knowledge transmission. The case study focuses on the languaging dynamics mobilised by the target teacher participant, who has been recognised as a representative of teaching excellence due to an international background and rich localised teaching experience. Aligned with the theoretical underpinnings of an embodied approach to learning from a constructivist perspective, this study focuses on the multimodal repertoire employed by the teacher's use of gestures to stimulate students' responses to the pedagogically designed high-order questions. We argue that this complementarity encourages thinking and active learning in the knowledge transfer. Further, this embodied interactive teaching mode with the affordances of gestures not only supports learning potential for information transmission but also affords action potentials for cognitive thinking and projected interaction for knowledge transformation in the active learning process.

Lai, Manhong, Du, Ping, and Lo, Leslie N. K.
- Abstract
This study investigates changes to academic work life under recent employment reform in the Chinese Mainland. It employs a mixed-methods research approach, first conducting a survey of 1,770 teachers at nine universities in Mainland China. These nine universities consist of first-tier, second-tier, and ordinary universities. Next, through a qualitative research approach, 60 teachers at three of the nine universities were interviewed. Teachers from the departments of management, information technology, education, and physics were interviewed, reflecting a variety of work conditions. Our study finds that the employment reform, with its stress on quantitative research output, has led to further restrictions on academic work and the standardization of academic development. The new measurements have led to a crisis of confidence and dignity for many senior teachers. Great pressure has also been placed on younger academics, who receive very limited promotion opportunities. This study offers a significant theoretical contribution to discussion on the changing academic work life and has policy implications for higher education personnel policy in China.

Lai, Manhong, Du, Ping, and Li, Linlin
- Abstract
In order to raise the international reputation and quality of higher education in "China", the Ministry of Education initiated new university employment reform, which pressed academics to produce more research. Recent employment reform has aggravated the conflict between teaching and research. This study "uses" mixed methods to investigate how academics perceived the employment reform and how they employed various strategies to handle teaching and research. Our study indicates a trend of deprofessionalization in academic work and an increasing tension between teaching and research. Handling teaching and research required a strong and conscientious effort on the part of academics. Concerted efforts should be made to offer a more supportive environment for academics to balance teaching and research.

Du, Ping, Lai, Manhong, and Lo, Leslie N. K.
- Abstract
Research on work life and job satisfaction of university professors is becoming an important research issue in the field of higher education. This study used questionnaires administered to 1 770 teachers from different levels, types, and academic fields of Chinese universities to investigate job satisfaction among university professors and the relationship between job satisfaction of university professors and the organizational characteristics of the university. The job satisfaction of Chinese university professors includes six dimensions: career development and school management, teaching and research services, salary, benefits and logistical services, professional reputation, teaching and research facilities, and the work itself. The overall job satisfaction levels are close to average, with salary and benefits receiving the lowest level of satisfaction. The organizational characteristics of universities, such as school type, school level, academic field, organizational climate, evaluation orientation, and school management, all have significant effects on the overall job satisfaction of university professors. The organizational climate and school level affect all six dimensions of job satisfaction among university professors.

Du, Ping
- Abstract
This study used sampling survey data from rural elementary schools in western China to analyze school adaptability, which is the representative noncognitive development of rural elementary students. It also investigated factors influencing the school adaptability of elementary school students at an individual and school level by using production function model and multilevel analysis. Research shows that (a) the overall development level of school adaptability of elementary school students in western China is relatively low, and gender and ethnicity differences exist; (b) school adaptability of elementary school students involves six factors: problem behavior, relationship with Chinese language teachers, relationship with math teachers, teachers' attitudes toward students, school satisfaction, and self-concept; and (c) students' families have an impact on the school adaptability of students. At the school level, teachers' conditions impact the school adaptability of rural elementary school students as well. (Contains 5 tables and 1 note.)

Phylogenetic analysis of a collection of 103 E1 gene sequences from rubella viruses isolated from 17 countries from 1961 to 2000 confirmed the existence of at least two genotypes. Rubella genotype I (RGI) isolates, predominant in Europe, Japan, and the Western Hemisphere, segregated into discrete subgenotypes; intercontinental subgenotypes present in the 1960s and 1970s were replaced by geographically restricted subgenotypes after ~1980. Recently, active subgenotypes include one in the United States and Latin America, one in China, and a third that apparently originated in Asia and spread to Europe and North America, starting in 1997, indicating the recent emergence of an intercontinental subgenotype. A virus that potentially arose as a recombinant between two RGI subgenotypes was discovered. Rubella genotype II (RGII) showed greater genetic diversity than did RGI and may actually consist of multiple genotypes. RGII viruses were limited to Asia and Europe; RGI viruses were also present in most of the countries where RGII viruses were isolated.

Myeloid leukemia factor 1-interacting protein (MLF1IP) has been found to be involved in the progression of several malignancies. The potential correlation between MLF1IP and clinical outcome in patients with luminal breast cancer, however, remains unknown. In the present study, we demonstrated that MLF1IP was significantly upregulated in luminal breast cancer tissue compared with adjacent normal tissue both in validated cohort and TCGA cohort. Upregulated expression of MLF1IP was correlated with more often lymph node metastasis and negative progesterone receptor expression in TCGA cohorts. Kaplan-Meier analysis indicated that patients with high MLF1IP expression had significantly lower overall survival. Moreover, multivariate analysis revealed that high MLF1IP expression was independent high risk factor as well as old age (>60) and distant metastasis. This study provides new insights and evidences that MLF1IP over-expression plays important roles in progression of luminal breast cancer. However, the precise cellular mechanisms for MLF1IP in luminal breast cancer need to be further explored.

Nitrite-dependent anaerobic methane oxidation (N-DAMO) is a recently discovered process linking the global carbon and nitrogen cycles. This process was reported to be mediated by "Candidatus Methylomirabilis oxyfera". To date, M. oxyfera-like bacteria have been detected in a limited number of freshwater habitats, but whether these bacteria occur in estuarine habitats is currently unknown. In this study, the distribution, diversity and abundance of M. oxyfera-like bacteria were studied in the sediment of the Jiaojiang Estuary of the East Sea (China). Both the 16S ribosomal RNA (rRNA) and pmoA genes confirmed the occurrence of M. oxyfera-like bacteria in the examined estuary. The recovered 16S rRNA gene sequences showed 91.5-97.2 % identity to the 16S rRNA gene of M. oxyfera, and the recovered pmoA gene sequences showed 85.1-95.4 % identity to the pmoA gene of M. oxyfera. Quantitative PCR further confirmed the occurrence of M. oxyfera-like bacteria in this estuary, with the abundance varying from 5.80 ± 0.28 × 10(4) to 8.35 ± 0.52 × 10(7) copies g (dry weight)(-1). Correlation analysis indicated that the sediment organic content was the most important factor affecting the distribution of M. oxyfera-like bacterial communities in the examined sediments among the environmental factors investigated. This study demonstrated for the first time the existence of M. oxyfera-like bacteria in an estuarine environment and showed the correlations between the distribution of these bacteria and the estuarine environmental conditions.

The prognosis of breast cancer occurs in young women is usually poor. Red cell distribution width (RDW), 1 of many routinely examined parameters, has recently been proposed as a prognostic marker in solid tumors. The aim of our study was to assess the predictive value of RDW for survival in young women with breast cancer. We reviewed 203 consecutive young female patients (under 40) with invasive breast cancer diagnosed at the First Affiliated Hospital of Wenzhou Medical University between January 2008 and December 2012. Preoperational RDW, clinicopathological information, and prognostic data were collected. RDW levels were divided into 2 groups: 161 patients with low RDW (≤13.75%) and 42 patients with high RDW (>13.75%). Clinicopathological differences between the 2 groups were calculated by chi-squared test and Wilcoxon rank-sum test. Kaplan–Meier survival analysis and Cox proportional hazard regression analyses were used to examine the effect of RDW on survival. We found that high RDW was significantly associated with larger tumor size (P = 0.002), positive lymph node metastases (P = 0.011), and advanced stages (P = 0.004). Patients with high RDW showed significantly lower disease-free survival (DFS; P

Poliomyelitis remains an important public health problem in China. Most cases and outbreaks are associated with wild type 1 polioviruses. To obtain an overview of type 1 poliovirus transmission in China, partial genomic sequences were compared for 24 case isolates from 12 provinces. Because polioviruses evolve rapidly during infection of humans, the genetic relationships among isolates provide a measure of the extent of epidemiologic linkage among cases. The observed genetic relationships were complex: six different genotypes, apparently derived from five separate endemic origins, were found. One genotype was recombinant, having noncapsid sequences derived from the Sabin type 1 vaccine strain and capsid sequences derived from a genotype indigenous to several northern and eastern provinces. Some isolates from geographically separate provinces were closely related; other isolates were related to wild polioviruses found in neighboring countries. The combination of epidemiologic and virologic analyses may facilitate the development of more effective strategies for poliomyelitis eradication.

Type 1 wild-vaccine recombinant polioviruses sharing a 367-nucleotide (nt) block of Sabin 1-derived sequence spanning the VP1 and 2A genes circulated widely in China from 1991 to 1993. We surveyed the sequence relationships among 34 wild-vaccine recombinants by comparing six genomic intervals: the conserved 5′-untranslated region (5′-UTR) (nt 186 to 639), the hypervariable portion of the 5′-UTR (nt 640 to 742), the VP4 and partial VP2 genes (nt 743 to 1176), the VP1 gene (nt 2480 to 3385), the 2A gene (nt 3386 to 3832), and the partial 3D gene (nt 6011 to 6544). The 5′-UTR, capsid (VP4-VP2 and VP1), and 2A sequence intervals had similar phylogenies. By contrast, the partial 3D sequences could be distributed into five divergent genetic classes. Most (25 of 34) of the wild-vaccine recombinant isolates showed no evidence of additional recombination beyond the initial wild-Sabin recombination event. Eight isolates from 1992 to 1993, however, appear to be derived from three independent additional recombination events, and one 1993 isolate was derived from two consecutive events. Complete genomic sequences of a representative isolate for each 3D sequence class demonstrated that these exchanges had occurred in the 2B, 2C, and 3D genes. The 3D gene sequences were not closely related to those of the Sabin strains or 53 diverse contemporary wild poliovirus isolates from China, but all were related to the 3D genes of species C enteroviruses. The appearance within approximately 2.5 years of five recombinant classes derived from a single ancestral infection illustrates the rapid emergence of new recombinants among circulating wild polioviruses.
