Short Report—The MDT Speed Date  [PDF]
Jenny Blythe
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.98093
Abstract: The importance of introducing both interprofessional education (IPE) and familiarity with the wider multidisciplinary team (MDT) roles cannot be underestimated in the undergraduate medical curriculum. This short report outlines an innovative method of teaching medical students about the role of the MDT in holistic patient management by way of a simulation “speed-date” and MDT meeting.
The Great Lapse: Climate Change, Water Resources and Economic Risks in the Great Lakes  [PDF]
Jenny Kehl
Journal of Water Resource and Protection (JWARP) , 2018, DOI: 10.4236/jwarp.2018.1011065
Abstract: The striking vastness of the world’s largest surface freshwater resource, the Laurentian Great Lakes, has generated the fallacy that they are not highly vulnerable to climate change. This fallacy has created a great lapse in our research and understanding of the effects of climate change on the Great Lakes, which are approaching critical environmental thresholds and jeopardizing ecosystem services. This article takes the novel approach of correcting the disconnect between the perception of vastness and the reality of vulnerability to climate change in the Great Lakes, and takes an additional novel step to link the water risks with the economic risks. The primary purpose is to demonstrate the interdependence of the freshwater ecosystem services affected by climate change with the economies that are highly dependent on those freshwater services in the Great Lakes region. Although many believe that environmental science or ethical arguments should be sufficient to warrant action on climate change, evidence shows that policy-makers are not compelled to generate advances unless there are strong economic components. This article highlights the leading edge of climate science for the Great Lakes, having conducted 32 in depth interviews with experts in microbiology, ecology, and limnology, among others, but it also adds substantively to previous work by providing economic evidence of water risks in the agricultural sector and energy sector, which constitute over $6 trillion in value and jobs that are specifically dependent on lakes waters. The article concludes by articulating three specific conclusions: the economic viability of the agricultural sector and the energy sector are jeopardized by loss of federal funding for climate change adaptation in the water sector; the existing policies such as between sectors such as the Farm Bill and Energy Future Bill are mal-aligned and should be aligned with the water sector; and negative environmental externalities including factors that exacerbate climate change should be incorporated into the true cost of water so we can more accurately conduct ecosystem valuation and, thus, address the true economic and environmental cost of climate change on the Great Lakes and our greatest water resources.

Complete Solutions to Mixed Integer Programming  [PDF]
Ning Ruan
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.33B005

This paper considers a new canonical duality theory for solving mixed integer quadratic programming problem. It shows that this well-known NP-hard problem can be converted into concave maximization dual problems without duality gap. And the dual problems can be solved, under certain conditions, by polynomial algorithms.

The Internal Structure of Sha-henda: A Morphological Perspective  [PDF]
Jiacing Ruan
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.44045
Abstract: Sha-henda (殺很大) “kill-very-big” which is coined from an advertisement of an on-line game has been being recently very popular in Taiwan society. With the effect of this slogan, people tends to analogize more and more new expressions, for example: sheng-henda (省很大) “save-very-big”, shui-henda (睡很大) “sleep-very-big”, and etc. Until 2013, the quantity of the coined expressions is still increasing. In the previous studies of Shen (2009), Xiao (2009), Liu (2010) and Liu (2012) on the structure of X-henda (X-很大), the structure is highly productive, involves an extreme or exaggerative meaning, is featured of rising tone, stress, and lengthening, and is initiated with a verb or an adjective. This present study argues henda in X-henda is a bound form (or a particle (助詞); Chao, 1979), similar to qilai (起來) in X-qilai or bude (不得) in X-bude, especially without objects or objects-preceding. With Distributed Morphology, a derivational analysis of the X-henda structure indicates that the function of henda intensifies the effect of sha to the extreme degree with rising tone, stress and lengthening to perform exaggeration on the object (in a sentence). The results may further contribute to grammaticalization analyses, verb-complement structure analyses and Chinese language teaching.
Early Warning Effect of “Wearing Cap” and “Catching Cap” on the Company’s Risk Structure
—Empirical Research Based on Breakpoint Regression Design

Shuai Ruan
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.103068
Abstract: This paper takes the listed companies in China from 2010 to 2015 as samples, which uses the breakpoint regression design to analyze the change of risk structure and its possible mechanism of listed companies after wearing and removing hats. The results show that the short-term solvency of listed companies deteriorates after wearing hats, and the long-term liabilities increase significantly. R&D expenditure decreased significantly, and cash flow level deteriorated. Financial leverage and comprehensive leverage increased significantly, and the total market value of the company decreased significantly, which led to a significant deterioration in the short-term financial risk structure of the company after wearing a hat.
Augmentation Index Derived from Peripheral Arterial Tonometry Correlates with Cardiovascular Risk Factors
Eshan Patvardhan,Kevin S. Heffernan,Jenny Ruan,Michael Hession,Patrick Warner,Richard H. Karas,Jeffrey T. Kuvin
Cardiology Research and Practice , 2011, DOI: 10.4061/2011/253758
Abstract: Background. Augmentation index (AIx) is traditionally obtained from pressure waveforms via arterial applanation tonometry. We sought to evaluate the association between AIx obtained from peripheral arterial tonometry (PAT) with cardiovascular risk factors (CRF) and coronary artery disease (CAD). Methods. 186 patients were enrolled in the study. The presence or absence of CRFs and CAD was assessed in each subject. AIx was calculated by an automated algorithm averaging pulse wave amplitude data obtained via PAT. Central blood pressures were assessed in a subset of patients undergoing clinically indicated cardiac catheterization. Results. An association was observed between AIx and age, heart rate, systolic blood pressure, mean arterial pressure, pulse pressure, body weight and body mass index. AIx was significantly lower in patients with <3 CRFs compared to those with >5 CRFs (=.02). CAD
Empirical Verification of Swanson’s Caring Processes Found in Nursing Actions: Systematic Review  [PDF]
Mary Kalfoss, Jenny Owe
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.511104
Abstract: Caring has long been recognized as central to nursing and is increasingly posited as a core concept although developing a theoretical description of caring which is adequate in the 21st. century continues to be a difficult task for nursing scholars. 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.
High-Accuracy Identification of Incident HIV-1 Infections Using a Sequence Clustering Based Diversity Measure
Xia-Yu Xia, Meng Ge, Jenny H. Hsi, Xiang He, Yu-Hua Ruan, Zhi-Xin Wang, Yi-Ming Shao, Xian-Ming Pan
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0100081
Abstract: Accurate estimates of HIV-1 incidence are essential for monitoring epidemic trends and evaluating intervention efforts. However, the long asymptomatic stage of HIV-1 infection makes it difficult to effectively distinguish incident infections from chronic ones. Current incidence assays based on serology or viral sequence diversity are both still lacking in accuracy. In the present work, a sequence clustering based diversity (SCBD) assay was devised by utilizing the fact that viral sequences derived from each transmitted/founder (T/F) strain tend to cluster together at early stage, and that only the intra-cluster diversity is correlated with the time since HIV-1 infection. The dot-matrix pairwise alignment was used to eliminate the disproportional impact of insertion/deletions (indels) and recombination events, and so was the proportion of clusterable sequences (Pc) as an index to identify late chronic infections with declined viral genetic diversity. Tested on a dataset containing 398 incident and 163 chronic infection cases collected from the Los Alamos HIV database (last modified 2/8/2012), our SCBD method achieved 99.5% sensitivity and 98.8% specificity, with an overall accuracy of 99.3%. Further analysis and evaluation also suggested its performance was not affected by host factors such as the viral subtypes and transmission routes. The SCBD method demonstrated the potential of sequencing based techniques to become useful for identifying incident infections. Its use may be most advantageous for settings with low to moderate incidence relative to available resources.

FEL-H Robust Control Real-Time Scheduling  [PDF]
Bing Du, Chun Ruan
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.21010
Abstract: The existing scheduling algorithms cannot adequately support modern embedded real-time applications. An important challenge for future research is how to model and introduce control mechanisms to real-time systems to improve real-time performance, and to allow the system to adapt to changes in the environment, the workload, or to changes in the system architecture due to failures. In this paper, we pursue this goal by formulating and simulating new real-time scheduling models that enable us to easily analyse feedback scheduling with various constraints, overload and disturbance, and by designing a robust, adaptive scheduler that responds gracefully to overload with robust H∞ and feedback error learning control.

Shiqi Huang, Baihao Ruan
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.59085

This paper is to valuate the main factors that should be considered by TNCS (transnational corporations) when they want to choose a country as emerging market. The main factors include the advantages of TNCS as well as the key conditions of the country. This paper takes the Wal-Mart for example, as the Wal-Mart is the representative transnational corporation, which chose China as emerging market years ago, and grows to an efficient scale now. This paper firstly uses the Eclectic Theory to analyze the advantages of the Wal-Mart, and secondly uses the Porter diamond Model to analyze environment in China. The conclusion of report will get ideas for TNCS to evaluate whether a country is qualified for an emerging market more efficiently.
