Consequently, verifying existing theoretical structures of caring remains an ongoing challenge. The aim of this article is to provide empirical verification of the caring processes of “knowing,” “being with,” “doing for,” “enabling” and “maintaining belief” from Swanson’s Middle Range Caring Theory based on the categorization of nursing actions from a systematic literature review on care. Methods: A systematic literature review was conducted in the fields of nursing sciences, medicine and psychology. Purposeful sampling was carried out covering a period from 2003-2013. The final sample included 25 articles. Results: Major themes of nursing actions included “knowing” which consisted of centering, nurturing, informed understanding, assessment skills, communication and respect for individual differences. “Being with” was characterized by intimate relationship, connecting, presencing, emotional adaptability awareness of self/other and decentering. “Doing for” included competence, knowledge, professional/technical skills, helping actions, anticipatory, multidisciplinary and preserving dignity. “Enabling” was characterized by self care, commitment, complexity of care, appropriate communication, information/education, sharing power, enabling choice and ongoing validation. Finally, “maintaining belief” was characterized by spiritual being, humanistic view, harmonious balance, hope, love, and compassion, meaning, and religious and spiritual orientation. Conclusion: Empirical verification was shown for the caring processes described in Swanson’s Caring Theory grounded in concrete nursing actions.展开更多

Total length of the main shock fault is 114 km and seismic moment is about 1.4×10 20 N·m. The epicentre of the main shock is located at the southern part, near the intersection of the two bands. Accelerations of two aftershocks ( M L 5.5, M S 6.9 ) were used as empirical Green's functions to synthesize the accelerations of the main shock in near and far field. A method that small events and main shock are considered not satisfying the similarity relationship in the improved empirical Green's function is also applied in this paper. Peak values, duration and response spectra of synthesized accelerations in far field are in agreement with the observed records. The synthesized results in near field are also in agreement with the epicentral intensity distribution of the main shock. The results show that the peak acceleration of Tangshan earthquake in epicentral region exceeds 1.1 g. It is consistent with the peak accelerations recorded in some large earthquakes occurred in recent years.展开更多

Langtry proposed a correlation-based transition model in 2006, which was built strictly on local variables. However, two core correlations in the model had not been published until 2009. In this paper, after considerable analyses and discussions of the mechanism of this transition model and a series of numerical validations in the skin friction coefficient of flat plate boundary layers, a new correlation based on free-stream turbulence intensity is developed, and the empirical correlation of the transition onset momentum thickness Reynold number aiming at the hypersonic transition is improved. Low-speed/transonic airfoils and a hypersonic double wedge fiat are tested to prove the reliability and practicability of this correlation.展开更多
