A Pattern-Based Approach to Manage Model References
Model references play an important role in model integration, especially when models belonging to different domains are to be integrated. They are also needed in various model transformation tasks. In some cases, they need to be instantiated systematically, following certain rules. This calls for an instantiation specification of model references.
In this paper we propose a pattern-based approach for modeling, specifying, and finally applying model references. We represent model references as so-called collaboration patterns,
modeled as UML collaborations. We further describe the instantiation rules of collaboration patterns. A tool has been implemented for establishing the model references according to the specification, allowing the designer to assist in the process of semi-automated model reference instantiation. We demonstrate the usefulness of the approach and tools by applying them in designing Web service orchestrations
Exploring the workload balance effects of including continuity-based factors in nurse-patient assignments
Workload balance in nurse-patient assignments is important for ensuring quality in patient care. Unbalanced workloads can lead to high levels of nursing stress, medical errors, lower-quality outcomes, and higher costs. Studies have pro-posed assignment strategies based on patient acuity, location, and characteristics of specialized units. These methods do not address the part of workload associated with continuity in care coordination, and the potential benefits associated with continuity-based assignments. We present the results of a pilot simulation study comparing an acuity-oriented method to a continuity-based approach, using acuity as a measure of workload. Our results suggest that a purely continuity-based approach can result in skewed workloads when measured by patient acuity. In future work, we plan to consider hybrid methods, which may be able to provide the benefits of both continuity and acuity based methods
Tweeting as a Marketing Tool: A Field Experiment in the TV Industry
Ā© 2017, American Marketing Association. Many businesses today have adopted tweeting as a new form of product marketing. However, whether and how tweeting affects product demand remains inconclusive. The authors explore this question using a randomized field experiment on Sina Weibo, the top tweeting website in China. The authors collaborate with a major global media company and examine how the viewing of its TV shows is affected by (1) the media company's tweets about its shows, and (2) recruited Weibo influentials' retweets of the company tweets. The authors find that both company tweets and influential retweets increase show viewing, but in different ways. Company tweets directly boost viewing, whereas influential retweets increase viewing if the show tweet is informative. Meanwhile, influential retweets are more effective than company tweets in bringing new Weibo followers to the company, which indirectly increases viewing. The authors discuss recommendations on how to manage tweeting as a marketing tool.National Natural Science Foundation of China (No. 71372045)National Natural Science Foundation of China (No. 71602033
Based on the Integration of āInternet + Ideology and Politicsā, the Practice of Online and Offline Mixed Teaching Mode of Modern Medical Courses in Traditional Chinese Medicine Majors
The purpose of this paper is to explore how to implement the online and offline mixed teaching mode in the modern medical courses of TCM specialty under the guidance of the concept of āInternet + ideological and political integrationā, and to explore its practical experience and remarkable results. With the power of todayās Internet technology, we will organically integrate ideological and political education into the modern medicine course of traditional Chinese medicine, so as to effectively promote the overall cultivation of studentsā comprehensive quality, and further enhance the attraction of the course and educational benefits
Chemical sensors towards environmental toxic molecule monitoring: fluorescent probes for detection of thiophenol
Thiophenols, a family of important industrial chemicals, is highly toxic for aquatic organisms and human beings. Developing new chemical sensors with the merit of fast, low cost, portable, selective and sensitive, as well as visualizable signal output for efficient detection of thiophenols, is highly desirable. This spotlight article reviewed and discussed the current trend and statement of thiophenols-specific fluorescent probes. Moreover, the future outlook in this field was also stated.info:eu-repo/semantics/publishedVersio
Recognition of speed signs in uncertain and dynamic environments
The speed limit signs recognition directly affects the safety of autonomous vehicles. Vehicles are usually running in an uncertain and dynamic environment. The performance of the recognition system is affected by various factors such as the different sizes of pictures, illumination condition and position circumstances, which can lead to misclassification. This makes the speed sign recognition challengeable. To improve the recognition rate of the speed signs in such environments, this work firstly applies the method of the saliency target detection based on the background-absorbing Markov chain, to extract the node in an image, then uses SPP-CNN to classify the extracted nodes with ten-folder validation. The recognition rate is up to 9.32%, higher than that obtained directly by SPP-CNN working on raw dataset

Juvenile hormone regulates the shift from migrants to residents in adult oriental armyworm, Mythimna separata
In migratory insects, increasing evidence has demonstrated juvenile hormone (JH) is involved in regulating adult reproduction and flight. Our previous study demonstrated that the switch from migrants to residents in Mythimna separata could be induced by adverse environmental conditions during a sensitive period in adulthood (the first day post-emergence), but the role of JH in this switch is not clear. Here, we found a significantly different pattern of JH titers between migrants and residents, with migrants showing a slower release of JH during adulthood than residents. Application of JH analogue (JHA) in the 1-day-old adults, significantly accelerated adult reproduction and suppressed flight capacity. The pre-oviposition period and period of first oviposition of migrants treated with JHA were significantly shorter, while the total lifetime fecundity and mating percentage increased. The flight capacity and dorso-longitudinal muscle size of the migrants were decreased significantly when treated with JHA. The effect of JHA on reproduction and flight capacity indicate that JH titers during the sensitive period (first day post-emergence) regulates the shift from migrants to residents in M. separata
