Pupillometry Analysis of Rapid Serial Visual Presentation at Five Presentation Rates
2024年
In this study,the effect of presentation rates on pupil dilation is investigated for target recognition in the Rapid Serial Visual Presentation(RSVP)paradigm.In this experiment,the RSVP paradigm with five different presentation rates,including 50,80,100,150,and 200 ms,is designed.The pupillometry data of 15 subjects are collected and analyzed.The pupillometry results reveal that the peak and average amplitudes for pupil size and velocity at the 80-ms presentation rate are considerably higher than those at other presentation rates.The average amplitude of pupil acceleration at the 80-ms presentation rate is significantly higher than those at the other presentation rates.The latencies under 50-and 80-ms presentation rates are considerably lower than those of 100-,150-,and 200-ms presentation rates.Additionally,no considerable differences are observed in the peak,average amplitude,and latency of pupil size,pupil velocity,and acceleration under 100-,150-,and 200-ms presentation rates.These results reveal that with the increase in the presentation rate,pupil dilation first increases,then decreases,and later reaches saturation.The 80-ms presentation rate results in the largest point of pupil dilation.No correlation is observed between pupil dilation and recognition accuracy under the five presentation rates.

真学习还是假参与?——Presentation在高校课堂教学应用中的问题与改进
2024年
Presentation是目前国内高校教学改革中常用的教学形式之一,在各类学科教学中均有不同程度的应用。这种以增强教学双主体互动为主要特征的教学形式,在实际教学中呈现出学生课堂参与深度不足、学习收获不系统、课堂汇报“一言堂”等问题。学生学习是为了完成任务而非获得知识、学生习惯于服从教师权威而非批判性思考、教师教学准备不足与指导环节缺失,以及教学评价的评价主体与形式单一是造成Presenta-tion应用效果不佳的重要因素。提高Presentation的应用效果,需要强化对教学过程的管理,保障Presentation规范实施;改革学业评价方式,促进学生主动思考与合作学习;拓展教学资源供给,为学生自主与合作学习提供更多支持;鼓励教师开展教学行动研究,不断提高教学专业化水平。

Clinical Presentation and Treatment Outcomes of Pregnancy-Related Acute Kidney Injury among Pregnant Women Admitted at the Benjamin Mkapa Hospital in Tanzania
2024年
Background: Globally, PRAKI is among the leading causes of death in pregnant women. The prevalence, causes and outcome of this condition vary among countries due to differences in environmental, socioeconomic, and health delivery systems. The common causes that have been reported in several studies are PIH, Haemorrhages and Sepsis while the outcomes may be either complete renal recovery, progression to CKD and hence dialysis dependency or death. This study aimed at determining clinical presentation and treatment outcomes of Pregnancy-Related Acute Kidney Injury in Pregnant women admitted at the Benjamin Mkapa Hospital, Dodoma, Tanzania. Results: Out of 4007 pregnant women who were admitted to the maternity ward 51 pregnant women were found to have PRAKI. Of those with PRAKI, 74.5% were between 21 to 25 years. The leading causes of PRAKI were PPH 12 (23.53%), Eclampsia 12 (23.53%), and pre-eclampsia 12 (23.5%). Hemodialysis therapy was provided to 22 (43.1%) patients, 15 (29.4%) individuals recovered spontaneously with medical management and 14 (27.5%) missed haemodialysis therapy due to various reasons. The mortality due to PRAKI was 17 (33.3%). Conclusion and Recommendation: Pre-eclampsia/eclampsia and post-partum haemorrhage were found to be the main causes of PRAKI. The mortality related to PRAKI is high and Hemodialysis therapy is vital help to prevent deaths for pregnant women with PRAKI. Pregnant women who develop acute kidney injury should be followed closely and a nephrologist should be consulted early. Early referral should be done by the lower level facilities for all at-risk pregnant women to a specialized multidisciplinary health facility.

Myelopathy as a Presentation of Cervical Spine Metastasis: A Case Report
2024年
Cervical myelopathy is a consequence of spinal cord compression in the cervical spine. Degenerative cervical spondylosis, osteophytes, discosteophyte complex, degenerative spondylolisthesis and hypertrophy of ligamentum flavum are the main etiologies of cervical myelopathy. Metastasis to cervical spine could be a rare cause of cervical myelopathy. The present study is a case report;presented a 36-year-old male with severe pain in cervical region, gait disability and impairment in sensory and motor function of upper left extremity. The patient had a history of thyroidectomy and cervical lymph node dissection due to follicular thyroid carcinoma (FTC) with improper follow-ups. He was diagnosed with metastatic cervical myelopathy and underwent surgical treatment. Cervical myelopathy due to metastasis is a rare condition and only few cases have been reported so far. So myelopathies can be a complication of metastatic cancers, and it should be considered by health professionals.

Prepare a Presentation Like Stevee Jobs Fivesteps for effective rehearsals
2024年
When it comes to delivering extraordinary presentations,few could compete with Steve Jobs.“Steve was a natural,”according to Bill Gates on a recent episode of the podcast Armchair Expert With Dax Shepard.Since I wrote one of the most popular books on Steve Jobs's presentation style,my ears perked up when Gates called Jobs a“natural.”I know that Jobs improved over time because he practiced over and over.

交互式BIM述标在水运工程投标中的应用
2024年
针对水运工程投标过程中的BIM述标问题,进行述标需求分析、工具比选和方案可视化流程的研究。结合国内某水运项目投标过程中的BIM述标,采用国产某述标平台全面整合述标内容并发布离线述标文件的方法,解决述标过程中的多类型模型集成、多源数据资源整合、述标内容和方案整合、方案可视化和交互式汇报等问题,最终实现了结合BIM模型完成全部的述标工作。结论是国产化述标平台在水运工程BIM述标及交互式汇报中优势明显,可以满足当前阶段BIM述标的要求,该研究将为水运工程类似投标中的BIM述标提供借鉴和参考。

Rare Presentation of Meningioma as an External Auditory Canal Mass
2024年
This is a case of a 60-year-old male with a history of prior left middle fossa meningioma that was partially resected with an operative report noting diffuse attachment to the middle fossa floor. Gamma knife was recommended but he never completed this management. He then presented about eight years later with a mass from his left external auditory canal. It was reported that two years prior another surgeon operated on the left ear for a cholesteatoma. CT temporal bone showed complete opacification of left EAC, mastoid bowl, and remaining mastoid air cells. In addition, there were irregular bony/hyperostotic changes seen within the left sphenoid and temporal bone. There was dural thickening within the middle fossa adjacent to the previously described hyperostotic bony changes. A mastoidectomy and excision of mass revealed extensive adhesive tissue throughout the middle ear, and mastoid up to the tegmen. Pathology of the portions that were resected confirmed Grade 1 meningioma. Stereotactic gamma knife radiation was completed to the area to prevent further growth. This case highlights extracranial meningioma that did not have definitive management for prior middle fossa floor meningioma. It also highlights the need to think of less common pathology in the middle ear and external auditory canal.

从“他者建构”到“自我呈现”:B站中女博士形象呈现分析
2024年
大众媒介时期,“女博士”群体总被冠以“大龄”“愁嫁”“第三性”等负面标签,形象被歧化。短视频的兴起促使其由“后台”走向“前台”,重构自我形象。本研究通过对B站女博士呈现视频探究后发现,女博士在B站呈现了“积极进取、投身学术的科研人”“不惧困难、愈挫愈勇的孤勇者”“追求婚恋平等与尊重的新兴女性”“乐于分享,释疑解惑的布道者”四类形象,多元化的形象为破除大众刻板印象、消解社会偏见、帮助更多女性投身科研工作起到了积极作用。然而,研究亦发现女博士呈现视频存在“理想化”倾向,表现在凝视下的形象“捯饬”,正向期待的情绪劳动,负向质疑下的反向呈现,致使“女博士”形象仍存在“失真”风险。为此,本研究提出要想真正消解社会对不同群体的刻板印象,不仅需要依靠“呈现主体”的觉醒,还需要“观者”的理性认知,如此才能防患从“大众媒介”时期的负面刻画转向“新媒体”时期的理想化印象。

商家自我呈现能够增强顾客的感知信任吗?——基于模特图片呈现特征的研究
2024年
在商家与顾客信息交互过程中,模特图片呈现特征对于顾客感知信任的影响。研究表明:模特的图片呈现(有无真人模特、模特的肤色、模特的体型)正向影响顾客的感知信任,并且感知相似性在模特图片呈现特征对顾客感知信任的影响中起到部分中介作用;网购平台的可信度和互动性、顾客的心理模拟以及信任倾向正向调节模特图片呈现对感知信任的影响,且均正向调节感知相似性的中介作用。文章有利于缓解社会身材焦虑现象,丰富了线上商务活动中消费者行为学的研究,对于消费者的信任产生机制进行探讨,并进一步丰富了视觉营销理论,对商家的自我呈现进行有效的指导,也可以为网络商家进行有效的产品图片展示提供理论参考。
