A different type of dirty work: Hidden taint,intersectionality, and emotion management in bureaucratic organizations     

Shawna Malvini Redden 《Communication monographs》2018,85(2):224-244

This study explores the intersectionality among identity markers, such as gender, race, and class, and emotion management in two bureaucratic organizations – municipal courtrooms and airport security checkpoints. We name and explore a new type of dirty work called “hidden taint,” which we describe as a larger, encompassing category of dirty work that involves the experience and dynamic co-construction of taint. Utilizing qualitative methods including participant observation and interviews, we compare how hidden taint is experienced in each bureaucratic context. The results focus on the relationship between (1) hidden taint and the co-construction of emotion norms and (2) hidden taint and power dynamics. This study extends communication theory by naming and describing hidden taint as a new type of dirty work, extending literature on emotion management and intersectionality by exploring their connection to dirty work in occupations with varying levels of prestige, and detailing how emotion management is co-constructed between employees and patrons in bureaucratic contexts.  相似文献

Precision measurement of the Newtonian gravitational constant     

Chao Xue  Jian-Ping Liu  Qing Li  Jun-Fei Wu  Shan-Qing Yang  Qi Liu  Cheng-Gang Shao  Liang-Cheng Tu  Zhong-Kun Hu  Jun Luo 《国家科学评论(英文版)》2020,7(12):1803

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.  相似文献

Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor     

Haicheng Li  Yinji Ma  Ziwei Liang  Zhouheng Wang  Yu Cao  Yuan Xu  Hua Zhou  Bingwei Lu  Ying Chen  Zhiyuan Han  Shisheng Cai  Xue Feng 《国家科学评论(英文版)》2020,7(5):849

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.  相似文献   

Preparing the Next Generation of Educational Measurement Specialists: A Call for Programs With an Integrated Scope and Sequence     

Mike Russell  Larry Ludlow  Laura O'Dwyer 《Educational Measurement》2019,38(4):78-86

The field of educational measurement has evolved considerably since the first doctoral programs were established. In response, programs have typically tacked on courses that address newly developed theories, methods, tools, and techniques. As our review of current programs evidences, this approach produces artificial distinctions among topics and techniques that are in fact a tightly coupled whole. This position paper advocates a redesign of the scope and sequence for doctoral programs focused on the preparation of the next generations of educational measurement specialists; a redesign that reflects the full life‐cycle of instrument development and use.  相似文献
