Using Corpus and Knowledge-Based Similarity Measure in Maximum Marginal Relevance for Meeting Summarization

MMR (Maximum Marginal Relevance) is widely used in summarization for its simplicity and efficacy, and has been demonstrated to achieve comparable performance to other approaches for meeting summarization. How to appropriately represent the similarity of two text segments is crucial in MMR. In this paper, we evaluate different similarity measures in the MMR framework for meeting summarization on the ICSI meeting corpus. We introduce a corpusbased measure to capture the similarity at the semantic level, and compare this method with cosine similarity and centroid score that only considers the salient words in the segments. Our experimental results evaluated by the ROUGE summarization metrics show that both the centroid score and the corpus-based similarity measure yield better performance than the commonly used cosine similarity. In addition, adding part-of-speech information in the corpus-based approach helps for the human transcripts condition, but not when using ASR output.

Initial-boundary value problem for 2D temperature-dependent tropical climate model

It is well known that the tropical climate model is an important model to describe the interaction of large scale flow fields and precipitation in the tropical atmosphere. In this paper, we address the issue of global well-posedness for 2D temperature-dependent tropical climate model in a smooth bounded domain. Through classical energy estimates and De Giorgi-Nash-Moser iteration method, we obtain the global existence and uniqueness of strong solution in classical energy spaces. Compared with Cauchy problem, we establish more delicate a priori estimates with exponential decay rates. To the best of our knowledge, this is the first result concerning the global well-posedness for the initial-boundary value problem in 2D tropical climate model.Comment: 20 page

ADAPTIVE REUSE OF THE URBAN BUILT ENVIRONMENT AND DESIGN INTERVENTION STRATEGIES

According to the World Cities Report 2020, global urbanization will continue to grow over the next ten years. At the same time, large cities are beginning to counter urbanization because of the continuous development of traffic conditions, the Internet, and other information technologies, which have created conditions for the migration and flow of population. The same thing is happening in the big eastern cities in China. On the one hand, the city needs to continue to expand; on the other hand, the original urban center is declining at the start. These pose severe challenges to Chinese cities regarding housing, infrastructure, and basic services. Today, numerous cities worldwide are attempting to transform into sustainable urban development to deal with urbanization, re-urbanization, and climate change. In this article, the term “adaptive reuse” is used as a research object to look for intervention methods to improve the built environment with unique social values and spatial characteristics. Firstly, The theoretical development process of adaptive reuse is chronologically organized. The built environment is divided into three categories: heritage buildings, existing buildings, and urban regeneration, to formulate the theoretical construction of adaptive reuse independently for each type. Second, we integrate prior researchers’ classifications of the built environment and intervention strategies with prominent cases of adaptive reuse in Europe and China. As a result, the three intervention strategies of this study and their respective designed intervention methods are outlined. In addition, each technique is followed by a matching practical case

International relations in international business research:A review and research agenda

The increasing dynamism of the international business (IB) environment has drawn greater scholarly attention to the implications of international politics for MNEs’ cross-border activities. However, a systematic overview of International Relations (IR) research which has been applied in IB studies is absent. To analyse this void, we propose a conceptual framework of the broader international context to delineate the research boundaries of the emerging IR in IB research domain and offer a critically synthesized review of the studies that have drawn on IRscholarship to explain MNEs’ behaviour. We conduct bibliometric and content analyses to understand the state of knowledge of IR in IB research and examine the main approaches to study the impact of IR factors on MNEs’ location choices, entry strategies, legitimacy and post-entry performance. By illuminating knowledge frontier issues, we derive important directions for deepening the integration of IR scholarship to advance IB research

Serum Sestrin2 and PlGF levels in pregnant women with pre-eclampsia and their correlations with the severity of the disease: A case-control study

Purpose: Sestrin2, a metabolic regulator with antioxidant activity, might have some certain predictability for the occurrence and severity of pre-eclampsia (PE). The purpose of this work was to explore the levels of serum Sestrin2 and PlGF in pregnant women with PE and their correlation with the severity index of the disease.Methods:This was a retrospective case-control study of pregnant women with PE who planned to give birth in our hospital from 05/2017 to 05/2019. Pearson correlation was used to analyze Sestrin2 and PlGF levels with PE severity. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of Sestrin2 and PlGF for PE.Results: There were 52 women in the control group, 46 in the mild PE group, and 36 in the severe PE group. As the severity of PE increased, the median levels of Sestrin2 increased (8.1, 9.8, and 11.8 ng/ml), and the levels of PlGF decreased (156, 117, and 67 pg/ml) in the three groups of women (all P<0.05).The levels of Sestrin2 and PlGF were strongly correlated with mean arterial pressure,proteinuria, newborn birth weight and gestational weeks at delivery (all P<0.001). Sestrin2 and PlGF had high efficiency of diagnosing PE (cut-off: 8.90 ng/ml, Area Under Curve [AUC]=0.979; cut-off: 122.50 pg/ml, AUC=0.963). Additionally, Sestrin2 and PlGF showed high value of severity prediction (cut-off: 11.15 ng/ml, AUC=0.857; cut-off: 68.50 pg/ml, AUC=0.837).Conclusion: Sestrin2 and PlGF are correlated with the severity of PE. Both Sestrin2 and PlGF had high value for PE diagnosis and severity prediction. Keywords: pre-eclampsia; Sestrin2; placental growth factor; oxidative stress; severity&nbsp

Effect of passive finger exercises on grip strength and the ability to perform activities of daily living for older people with dementia: a 12-week randomized controlled trial

Background: Dementia adds burden to society. As it is not curable, physical exercise activities are optimal to improve the physical strength and quality-of-life of people with dementia. Aim: Design, implementation, and examination of a set of passive finger exercises and their effects on improving grip strength and activities of daily living (ADL) for older people with dementia. Methods: Forty older people with dementia were recruited and randomly allocated into an experimental group and a control group, each with 20 people. The control group received routine nursing care. In addition to this, the experimental group received 25-minutes of passive finger exercises every day for 12 weeks. The health outcomes measured were grip strength and ADL, before and after the intervention. Grip strength was assessed by electrical hand muscle dynamometer. ADL were assessed with Barthel index. Results: Although there was no effect on grip strength, passive finger exercises led to significant improvements in urinary control, defecation function, and overall ADL in comparison with the control group. Implications for practice: Passive finger exercises can be integrated into physical exercise programs for older people with dementia to improve their urinary control, defecation function, and ADL
