Optimization Design of Structures Subjected to Transient Loads Using First and Second Derivatives of Dynamic Displacement and Stress by Qimao Liu, Jing Zhang, Liubin Yan

“…An algorithm of first and second derivatives of dynamic displacement and stress with respect to design variables is formulated based on the Newmark method. The inequality time-dependent constraint problem is converted into a sequence of appropriately formed time-independent unconstrained problems using the integral interior point penalty function method. …”

Damage Detection for Large-Scale Grid Structure Based on Virtual Axial Strain by Jian-xin Yu, Hui-feng Tan

“…Firstly, random signals were used for excitation and the damage was simulated by decreasing beam elasticity modulus. Then, the NEWMARK-β precision direct integral method was appreciated for calculating time history response. …”

Coping Strategies of Family Members of Hospitalized Psychiatric Patients by Phyllis M. Eaton, Bertha L. Davis, Pamela V. Hammond, Esther H. Condon, Zina T. McGee

“…In this paper, the coping strategies of 45 family members were examined using a descriptive, correlational, mixed method research approach. Guided by the Neuman Systems Model and using the Family Crisis Oriented Personal Evaluation Scales and semistructured interviews, this paper found that these family members used more emotion-focused coping strategies than problem-focused coping strategies. …”

Study on the Damping Mechanism of the Shrouded Blade considering Contact Features by Chaofeng Li, Tao Li, Ruihuan Qiao, Bangchun Wen

“…The influence of shroud structure’s parameters such as rotational speed, contact angle, friction coefficient, clearance, and shroud position on the damping effect of the shroud is reviewed by means of amplitude-frequency response and energy through the Newmark-β numerical method. The results demonstrate that the damping effect of the shroud by contact is more obvious than by friction and the amplitude-frequency curve of the shrouded blade shows a strong hard nonlinear phenomenon.…”

‘His Own Nearer Household Gods’: Pagans, Christians, and Marius the Epicurean’s Religious Hermeneutics by Jude Wright

“…Walter Pater’s Marius the Epicurean (1885) may be seen as part of the subgenre of the all but forgotten Historical Novel of Early Christianity, which is represented by such lights as Newman, Kingsley, and Wiseman. Yet, Pater’s novel is distinct from these others, for while it follows the familiar trajectory of works in this vein, tracing the progress of the eponymous protagonist from paganism to Christianity, Marius’s conversion is portrayed primarily as a movement across a spectrum of belief that is tied directly through aesthetics back to the pagan religiosity that Marius grew up participating in. …”

The widening gender wage gap in the gig economy in China: the impact of digitalisation by Jiachen Han, Mingming Li, Shi Li, Yingying Hu

“…Utilising the China Labour Dynamics Survey data from 2014, 2016, and 2018, and applying the Bourguignon, Fournier, and Gurgand model to correct selection bias, this study reveals that, digitalisation has exacerbated gender wage gaps, with the wage growth of female gig workers significantly lagging behind their male counterparts, especially among married and older cohorts. Adopting the Neumark decomposition, the analysis confirms that discrimination largely accounts for this gap. …”
