气候变化对安徽黄山市旅游的影响研究

旅游业对气候变化极为敏感。基于1956－2010年黄山市气候数据,采用旅游气候舒适度综合评价模型计算了黄山市气候舒适度;结合2007－2010年黄山市游客量数据,采用O L S方法建立气候舒适度指数与游客量指数间的回归模型。结果表明,气候变化对安徽省黄山市旅游产生影响显著。其中,对国内旅游市场的影响超过了对入境旅游市场的影响,气候舒适度指数每变化1单位,入境游客量指数变化1.25％,国内游客量指数变化1.49％。研究结果可为提出安徽旅游业应对气候变化策略提供科学依据。     

现代影视对古典名著改编的思考与启示

回顾历史,影视改编呈现出典型的时段、地域、文化等特征;古典名著也受到现代影视的促进而扩大了传播。但进入21世纪以来,科技含量越来越多的影视对古典名著的改编却走上了过分追求市场化和吸引观众眼球的弯路。因此,探求影视改编的新路和方向便成了当下学界讨论和研究的重点。     

Instrument adaptation in cross-cultural studies of students’ mathematics-related beliefs: learning from healthcare research

Much comparative research into education-related beliefs has exploited questionnaires developed in one culture for use in another. This has been particularly the case in mathematics education, the focus of this paper. In so doing, researchers have tended to assume that translation alone is sufficient to warrant a reliable and valid instrument for cross-cultural research, prompting concerns that a number of necessary equivalences are unlikely to have been addressed. In this paper, we consider the nature of these equivalences before examining the literature of a different field, healthcare research, to synthesise an approach to instrument adaptation that is pragmatic but rigorous. Finally, we demonstrate how this pragmatic approach, incorporating extensive cognitive interviews, enabled us to adapt and refine a mathematics-related beliefs questionnaire, developed in Flanders, for use with students aged 14–15 in England and Spain. Analyses indicate that the instrument so developed is multidimensional, reliable and cross-culturally valid. Some implications are discussed.

4~6岁幼儿移动性动作发展及神经肌肉控制研究

目的:研究4~6岁幼儿移动性动作发展的外在表现和神经肌肉控制的内在机制。方法:通过粗大动作发展测试(Test of Gross Motor Development-3,TGMD-3)对跑、蹦跳和单脚跳进行评价,用BTS表面肌电测试系统时域分析的方法对完成动作时肌肉的积分肌电(Integrated EMG,IEMG)和时序进行研究。采用方差分析探讨不同年龄移动性动作发展水平的差异,计算年龄组×不同肌肉对标准化iEMG的影响,年龄组×动作类型对标准化共收缩指数的影响,结果:4~6岁幼儿移动性动作发展水平和下肢肌群iEMG值存在年龄之间的差异性,其中单脚跳的差异性最为明显(P<0.05)。标准化iEMG值股直肌最大、胫骨前肌其次。随着年龄的增长和动作复杂程度的降低,股直肌/股二头肌和胫骨前肌/腓肠肌的共收缩指数峰值越来越大。结论:TGMD-3作为幼儿动作发展评价工具具有可行性,其中单脚跳可优先作为移动性动作技能定性评价指标,该动作下肢肌群iEMG值可作为定量评价的代表性指标。幼儿在跑、蹦跳和单脚跳动作时,主要用力肌肉为股直肌和胫骨前肌。随着年龄增长,完成移动性动作时,iEMG值逐渐增大,膝关节和踝关节周围肌群协调性逐渐增强。     

AdaSL: An Unsupervised Domain Adaptation framework for Arabic multi-dialectal Sequence Labeling

Dialectal Arabic (DA) refers to varieties of everyday spoken languages in the Arab world. These dialects differ according to the country and region of the speaker, and their textual content is constantly growing with the rise of social media networks and web blogs. Although research on Natural Language Processing (NLP) on standard Arabic, namely Modern Standard Arabic (MSA), has witnessed remarkable progress, research efforts on DA are rather limited. This is due to numerous challenges, such as the scarcity of labeled data as well as the nature and structure of DA. While some recent works have reached decent results on several DA sentence classification tasks, other complex tasks, such as sequence labeling, still suffer from weak performances when it comes to DA varieties with either a limited amount of labeled data or unlabeled data only. Besides, it has been shown that zero-shot transfer learning from models trained on MSA does not perform well on DA. In this paper, we introduce AdaSL, a new unsupervised domain adaptation framework for Arabic multi-dialectal sequence labeling, leveraging unlabeled DA data, labeled MSA data, and existing multilingual and Arabic Pre-trained Language Models (PLMs). The proposed framework relies on four key components: (1) domain adaptive fine-tuning of multilingual/MSA language models on unlabeled DA data, (2) sub-word embedding pooling, (3) iterative self-training on unlabeled DA data, and (4) iterative DA and MSA distribution alignment. We evaluate our framework on multi-dialectal Named Entity Recognition (NER) and Part-of-Speech (POS) tagging tasks.The overall results show that the zero-shot transfer learning, using our proposed framework, boosts the performance of the multilingual PLMs by 40.87% in macro-F1 score for the NER task, while it boosts the accuracy by 6.95% for the POS tagging task. For the Arabic PLMs, our proposed framework increases performance by 16.18% macro-F1 for the NER task and 2.22% accuracy for the POS tagging task, and thus, achieving new state-of-the-art zero-shot transfer learning performance for Arabic multi-dialectal sequence labeling.
