As an exciton feedback layer （EFL）, the BAlq does not act as a traditional hole blocking effect. The design of this kind of device structure can greatly reduce excitons＇ quenching due to accumulated space charge at the exciton formation interface. Meanwhile, the non-radiative energy transfer from EFL to the EML can also be utilized to enhance the excitons＇ formation, which is confirmed by the test of photolumimescent transient lifetime decay and electroluminescence enhancement of these devices. Accordingly, the optimal device presents the improved performances with the maximum current efficiency of 4.2 cd/A and the luminance of 24600cd/m2, which are about 1.45 times and 1.75 times higher than those of device A （control device） without the EFL, respectively. Simultaneously, the device shows an excellent color stability with a tiny offset of the CIE coordinates （△x = ±0.003, △y = ±0.004） and a relatively lower efficiency roll-off of 26.2% under the driving voltage varying from 3 V to 10 V.展开更多

Here we design an ＇electrically written and optically read＇ information storage device employing BiFeO3/A u heterostruetures with strong absorption resonance. The electro- optic effect is the basis for the device design, which arises from the strong absorption resonance in BiFeO3/Au heterostructures and the electrically tunable significant birefringence of the BiFeO3 film. We first construct a sim- ulation calculation of the BiFeO3/Au structure spectrum and identify absorption resonance and electro-optical modulation characteristics. Following a micro scale partition, the surface reflected light intensity of different polarization units is calculated. The results depend on electric polarization states of the BiFeO3 film, thus BiFeO3/Au heterostructures can essentially be designed as a type of electrically written and optically read infor- mation storage device by utilizing the scanning near-field optical microscopy technology based on the conductive silicon cantilever tip with nanofabricated aperture. This work will shed light on information storage technology.展开更多

Critical coupling is achieved when the resonator intrinsic loss is perfectly balanced by the external coupling enabled by a Mach–Zehnder interferometer coupler. The high suppression of the carrier leads to a clean two-tone optical signal with the frequency interval two times larger than that of the input microwave frequency.The beating of the two-tone signal at a photodiode generates the frequency upconverted microwave signal.A theoretical model is established to analyze the modulation process and the microwave signal generation.Experimental results show that the electrical harmonic suppression ratio is around ~20 dB(29 dB) for an input microwave signal with 5 dBm(10 dBm) power.展开更多

In addition, the error-floor level originating from the uncoded system is suppressed.展开更多

文摘Background:Employment can support the recovery of individuals with Severe Mental Disorders by promoting autonomy,reducing hospital admissions and associated costs,fostering social connections,and providing structure to their daily lives.The objective of this pilot study was to analyse job satisfaction and perceived social support in people with severe mental disorders who are users of an Employment Guidance and Support Service in southern Spain.Methods:A descriptive cross-sectional pilot study was carried out with a sample of 39 workers with mental disorders from the province of Huelva(southern Spain)who were users of the Employment Guidance and Support Service of the Regional Government of Andalusia(Spain).Perceived Organisational Support was assessed with the Spanish short version of the Survey of Perceived Organizational Support and the S10/12 Job Satisfaction Questionnaire.Results:As findings,87.2%of the sample reported high levels of job satisfaction,and 61.5%of the subjects surveyed perceived high levels of support.Regarding the variable Perceived Support,84%of workers from ordinary companies and 50%of those from Special Employment Centres(SECs)considered that they had sufficient support.There was a positive correlation between support and satisfaction(Spearman’s Rho=0.423).Conclusion:The results suggest a positive relationship between support and satisfaction,warranting further longitudinal research with larger samples.This pilot study provides preliminary insights into the relationship between perceived organizational support and job satisfaction among workers with severe mental disorders.

文摘This study explored the relationship between perceived social support and employment anxiety among Chinese college students,as well as the mediating and moderating effects of psychological resilience and career adaptability on this relationship.A total of 1928 college students(females=1371,mean age=20.42,SD=1.05)completed the Perceived Social Support Scale,Employment Anxiety Questionnaire,Connor-Davidson Resilience Scale and Career Adapt-Abilities Scale.Mediation analysis results showed that psychological resilience mediated the relationship between perceived social support and employment anxiety for lower employment anxiety.Career adaptability moderated the mediating effect of psychological resilience for lower employment anxiety than with either of the variables alone.Thefindings are consistent with cognitive diathesis-stress theory and career construction theory which propose that individuals’cognitive structures and psychological predispositions interact with environmental stressors to shape their career development and psychological well-being.Essentially,students who have a robust social support system,high career adaptability,and are psychologically resilient are less likely to experience employment anxiety.

文摘Objective:The objective of this research is to thoroughly investigate the extent of mutual interference among clinical internships,postgraduate entrance examinations,and employment by examining engineering contradictions,thus offering theoretical insights and guidance for medical students to attain high-quality outcomes in clinical internships.Methods:A combination of literature reviews,questionnaires,interviews,and observations of internships was utilized,followed by a statistical analysis to assess the levels of interference among the three factors.Results:The senior participants achieved significantly higher scores than their junior counterparts in evaluations of comprehensive humanistic quality,understanding professional values,communication abilities,clinical skills,and attitudes towards learning,with differences that were statistically significant(p<0.05).After applying an interactive training approach that merges early clinical practice with foundational medical education,both groups displayed notable enhancements in activity content,formats,instructor attitudes,clinical performance,and the blending of theory with practice(p<0.05).Conclusion:By emphasizing‘early clinical’education,students are effectively engaged in clinical practice through active involvement,leading to feedback-oriented training.This strategy not only improves the overall quality of internships but also reduces the risk of scheduling conflicts with postgraduate entrance examinations and employment opportunities.

文摘This study investigated proactive personality effects on employment preparation and the mediating roles of self-efficacy and career exploration behaviors in this relationship.The study sample comprised 445 university students(68.3%female;aged 20 to 24)from a university in central China.The participants completed measures to assess proactive personality,employment preparation,self-efficacy,and career exploration behaviors.Structural equation modeling analysis results indicated that proactive personality predicted higher employment preparation;Self-efficacy and career exploration behaviors partially mediated this relationship.Specifically,career exploration behaviors had a stronger mediating effect than self-efficacy on the total effect(34.71%vs.28.89%).The findings suggest proactive personality is key to employment preparation through self-belief and willingness to explore the job market.Higher education career counseling and mental health education programs should provide targeted training to promote career exploration by the student’s personal attributes for best match employment preparation.
