送你以想象的翅膀——芭蕾舞剧《精卫》音乐点评

天津芭蕾舞剧团创作的芭蕾舞剧<精卫>已来京公演,由中央音乐学院教授唐建平作曲. 据中国古老的<山海经>记载,精卫是一种神鸟,她娇小美丽,是炎帝的小女儿.所以她既不同于外国芭蕾中的天鹅,也不具备庄子笔下"鲲鹏"展翅九万里那样磅礴的气势.

从弹词《精卫石》看秋瑾的理想世界

《精卫石》是秋瑾创作的带有自传性特点的弹词,女主人公黄鞠瑞是其化身。在这部弹词中客观纪实与理想虚构并存。在婚姻方面,女主人公黄鞠瑞遭遇才女俗子式不幸婚配,但因留学而悖逆贤妻良母的传统角色,寄托秋瑾对自由婚姻的向往;在拯救女界方面,维新思想浸染下的黄鞠瑞蜕变为女子独立自主的启蒙者,为了能引导庭院空间的女子走出闺门,她淡化留学的艰难和渲染日本女学的进步性;在救国方面,黄鞠瑞留学期间加入光复会,摒弃性别偏见而无惧生死,在男女共同努力下实现了同建共和的愿望。可以说,这部作品女主人公从伤己到救群救国的成功演绎,不仅是秋瑾借女性化倾向明显的弹词书写自我人生,而且折射出在晚清男女平等思想浸透下女性由传统家庭贤妻良母到国民身份跨越的理想化进程。

闺中无静女——晚清女作家弹词与“振兴女权”

清代女作家弹词是指以女性作家为主体的创作形式和案头文本 ,而并非流行在江南一带的市井演艺形态。 184 0年到 1910年之间的女作家弹词创作更多地凸现了女作家的时代意识 ,在社会大变迁到来之际 ,以女史的昂扬姿态 ,生发出揭发世情世态、论世救世之主张 ,而辛亥革命前夕女革命家秋瑾创作的《精卫石》标志着弹词小说“振兴女权”

Modified algorithm of combined GPS/GLONASS precise point positioning for applications in open-pit mines

A modified algorithm of combined GPS/GLONASS precise point positioning （GG-PPP） was developed by decreasing the number of unknowns to be estimated so that accurate position solutions can be achieved in the case of less number of visible satellites. The system time difference between GPS and GLONASS （STDGG） and zenith tropospheric delay （ZTD） values were firstly estimated in an open sky condition using the traditional GG-PPP algorithm. Then, they were used as a priori known values in the modified algorithm instead of estimating them as unknowns. The proposed algorithm was tested using observations collected at BJFS station in a simulated open-pit mine environment. The results show that the position filter converges much faster to a stable value in all three coordinate components using the modified algorithm than using the traditional algorithm. The modified algorithm achieves higher positioning accuracy as well. The accuracy improvement in the horizontal direction and vertical direction reaches 69% and 95% at a satellite elevation mask angle of 50°, respectively.

Optimization model of GNSS/pseudolites structure design for open-pit mine positioning

A new pseudolites （PLs） structure optimization model of global navigation satellite system （GNSS）/PLs integration positioning system used in deep open-pit mine was presented. Position dilution of precision （Pdop） and reliability were selected as the optimization indicators to build a multi-objective optimization model to decide the optimum PLs location. A scheme was designed by establishing a four-dimensional model taking azimuth （a）, elevation angle （e） and epoch （t） of satellites as the input independent variables and Pdop as the dependent variable to calculate the optimum PLs location zone considering the real circumstances. And then the ultimate PLs location can be fixed by testing the curves of Pdop along time. A field collected Trimble R8 GPS data set in China University of Mining and Technology （CUMT） campus was used for the model test to show the effectiveness, and the proposed PLs optimum design scheme was used at the west open-pit mine of Fushun mining group Co., Ltd., in China, better Pdop and reliability have been achieved for the integration system. Both experiments show that the proposed scheme is excellent in designing GNSS/PLs system which is helpful for improving the performance of the positioning system and reducing the cost.

On simulation of precise orbit determination of HY-2 with centimeter precision based on satellite-borne GPS technique

The HY-2 satellite carrying a satellite-borne GPS receiver is the first Chinese radar altimeter satellite, whose radial orbit determination precision must reach the centimeter level. Now HY-2 is in the test phase so that the observations are not openly released. In order to study the precise orbit determination precision and procedure for HY-2 based on the satellite- borne GPS technique, the satellite-borne GPS data are simulated in this paper. The HY-2 satellite-borne GPS antenna can receive at least seven GPS satellites each epoch, which can validate the GPS receiver and antenna design. What＇s more, the precise orbit determination processing flow is given and precise orbit determination experiments are conducted using the HY-2-borne GPS data with both the reduced-dynamic method and the kinematic geometry method. With the 1 and 3 mm phase data random errors, the radial orbit determination precision can achieve the centimeter level using these two methods and the kinematic orbit accuracy is slightly lower than that of the reduced-dynamic orbit. The earth gravity field model is an important factor which seriously affects the precise orbit determination of altimeter satellites. The reduced-dynamic orbit determination experiments are made with different earth gravity field models, such as EIGEN2, EGM96, TEG4, and GEMT3. Using a large number of high precision satellite-bome GPS data, the HY-2 precise orbit determination can reach the centimeter level with commonly used earth gravity field models up to above 50 degrees and orders.

Caregiver burden:A concept analysis

Objective:Caregiver burden is used frequently within the nursing literature.It has not yet been clearly defined as there are different opinions regarding this concept.The purpose of this paper is to provide clarity surrounding the concept caregiver burden.Methods:An electronic search of MEDLINE,CINAHL,Health Source Nursing/Academic Edition and Academic Search Complete(ASC)of EBSCO,China National Knowledge Infrastructure(CNKI)and Google Scholar were searched with a limit of 10 years and published in the English or Chinese language.The paper adopted the framework by Walker and Avant.The attributes,antecedents,consequences and uses of the concept were identified.Results:At total of 33 articles were included.The three attributes of caregiver burden were identified as self-perception,multifaceted strain,and over time.The antecedents included insufficient financial resources,multiple responsibility conflict,lack of social activities.The consequences of caregiver burden resulted in negative change which included decreased care provision,decrease in quality of life,physical and psychological health deterioration.Conclusion:A definition of caregiver burden was developed.Tools to measure caregiver burden were identified.The findings from this analysis can be used in nursing practice,nursing education,research and administration.

Exploring the employment readiness and return to work status of breast cancer patients and related factors

Objective:To investigate the employment status,employment readiness,and other factors affecting the ease or difficulty with which breast cancer patients effect their return to work(RTW).Methods:This study adopted a mixed-method design,recruiting participants from among breast cancer patients in a cancer hospital in Hunan from December 2018 to June 2019.We approached 300 individuals,192 of whom ultimately participated in this study.The quantitative part of the study involved several scales:the Patient Health Questionnaire-9(PHQ-9),the Brief Fatigue Inventory(BFI),the Work Ability Index(WAI),and the Lam Assessment of Employment Readiness(LASER).The qualitative part involved a set of open-ended questions and written responses collected from 41 participants who had already returned to work at the time of data collection.Their written responses mainly concerned factors influencing RTW.Results:Forty-one breast cancer patients had returned to work.The results reported a median total Cognitive Symptom Checklist score of 9.00(6.00,15.25),a median WAI score of 5.00(3.50,9.75),a median BFI score of 26.00(14.75,42.00),a median total PHQ-9 score of 8.00(5.25,17.00),and a LASER score of 50.35±11.90.Multiple regression analysis showed that the participants’cancer stage,cognitive limitations,depression,fatigue,and work ability were significant predictors of employment readiness(P<0.05).Exploring the qualitative data,we found that higher skill levels,better social support,and a flexible work schedule facilitated RTW;stress,lack of confidence in one’s work skills,depression,and fatigue are all possible barriers to RTW.Conclusion:The findings indicate that breast cancer patients have a low level of employment readiness.Nurses and other healthcare providers can develop relevant interventions to promote employment readiness and ultimately achieve RTW in this study population.

Development and validation of the Nurse’s Workplace Mental Health Questionnaire

Objectives:This study aimed to develop and validate the Nurse’sWorkplace Mental Health Questionnaire(NWMHQ).Methods:The questionnaire was developed based on the two continua model of mental illness and health proposed by Keyes.The initial questionnaire was generated through literature review,two rounds of Delphi expert consultation,followed by a pilot survey.Finally,the reliability and validity of the questionnaire were validated through an online survey of 2,815 registered nurses selected from the public hospitals in 11 provinces from June to July 2020.Results:The item-content validity index(I-CVI)of the questionnaire ranged from 0.750 to 1.000 and the average scale-level content validity index(S-CVI/Ave)was 0.906.Cronbach’s a coefficient was 0.948 and test-retest reliability was 0.850.The self-rating depression scale score was negatively related to the NWMHQ score(r=0.664,P<0.01).The exploratory factor analysis(EFA)yielded six factors(emotional status,psychological security,positive relationship,resilience,self-efficacy,and subjective well-being),consisting of 32 items.The cumulative variance contribution rate was 65.58%.Confirmatory factor analysis(CFA)showed an acceptable fit.Conclusion:The NWMHQ developed in this study showed good reliability and validity.This questionnaire may help assess the mental health status of nurses and help nursing managers to develop appropriate targeted psychological interventions.

Self-endangering:A qualitative study on psychological mechanisms underlying nurses’burnout in long-term care

Objectives To develop a more specific understanding of psychological mechanisms in the development of burnout in long-term care as a basis for potential new intervention strategies aiming at improving nurses’mental health.Methods Two qualitative studies with thematic analysis were conducted.In Study 1,we conducted eight group interviews with 110 nurses from May–July 2019 in the context of workshops at eight nursing homes in Germany.In Study 2,we supplemented these with semi-structured interviews with 14 executives at German nursing homes in December 2019.Results The thematic analysis in Study 1 identified three main themes:causes of challenges,employees’opportunities for change,and organisational opportunities for change.Thematic analysis in Study 2 identified three main themes:job motives,reasons for filling in for others,and employee self-care.Further,our results show that the need to stand in for colleagues,in particular,is one of the greatest challenges for geriatric caregivers.In dealing with these challenges we found that self-endangering behaviour—a diminished ability to say no when asked to fill in or to do work overtime—was an important antecedent of nurses’burnout.Further,high levels of altruistic motivation and identification with the team or organisation were associated with self-endangering behaviour in the presence of adverse working conditions.Low levels of self-worth are a further risk factor for self-endangering.Conclusions Our findings are at odds with some core tenets of classic models of job demands and burnout that construe motivation and identification as resources.Our results show the need of a holistic intervention program in nursing including individual coaching,team-based interventions and organisational development processes.Employees themselves should be sensitized to this issue and supported in the long term,and politicians should create structures that do not encourage this behaviour any further.

High Precision Orbit Determination of CHAMP Satellite
