The increasing need for readily available mental health services, coupled with the swift advancement of novel technologies, prompts conversations over the viability of psychotherapy approaches using engagements with AI. Despite the positive impacts, there are recognizable drawbacks associated with the application of AI in psychotherapy. Establishing a therapeutic alliance is difficult for non-human entities. Psychotherapy is a task too complex for limited artificial intelligence. AI appears capable of handling jobs that are clearly defined and relatively straightforward. Besides, AI malfunctions, data confidentiality, informed consent, and risk of bias are potential concerns. We present a literature update of possible solutions to overcome these concerns.展开更多

The axonal regeneration of the adult CNS is generally low, and it is addi- tionally restricted after injury by the presence of inhibitory mol- ecules, generated by the glial scar.展开更多

Making full use of this method will bring great benefits for English teaching. Besides the unique advantages and the present situations of multimedia applied in English teaching, it is more important for us to find out its drawbacks in practical teaching process, such as the ineffective application of multimedia by teachers. Then, the related strategies mast be put forward improving the teaching facilities of multimedia. This paper mainly discusses the related strategies in order to create a better teaching environment and facilitate the training of teachers. After studying this paper, we will have a good knowledge of the multimedia teaching. Consequently, we can apply the multimedia into the traditional teaching. Multimedia resources are also very useful for teachers to meet the requirements in our modem society. Meanwhile, it will promote the teaching reform and improve the level of education in our country.展开更多

PPP approach, referring to the method of Presentation, Practice and Production, is one of the traditional language teaching instructions in classroom. There are advantages and drawbacks using PPP to teach grammar. It can benefit both L2 teachers and learners whereas it limits learner autonomy and the interaction among learners in language grammar teaching classroom.展开更多

AI is exhibiting a practical tool in the healthcare industry in patient care. The objective of this current review is to assess and analyze the use of AI and its use in orthopedic practice, as well as its applications, limitations, and pitfalls. Methods: A review of all relevant databases such as EMBASE, Cochrane Database of Systematic Reviews, MEDLINE, Science Citation Index, Scopus, and Web of Science with keywords of AI, orthopedic surgery, applications, and drawbacks. All related articles on AI and orthopaedic practice were reviewed. A total of 3210 articles were included in the review. Results: The data from 351 studies were analyzed where in orthopedic surgery. AI is being used for diagnostic procedures, radiological diagnosis, models of clinical care, and utilization of hospital and bed resources. AI has also taken a chunk of share in assisted robotic orthopaedic surgery. Conclusions: AI has now become part of the orthopedic practice and will further increase its stake in the healthcare industry. Nonetheless, clinicians should remain aware of AI’s serious limitations and pitfalls and consider the drawbacks and errors in its use.展开更多

This paper examines the revenue-constrained optimal tariff structure in a small open economy including a duty drawback as a trade policy tool. This paper has two main aims. First, we show that the revenue-constrained optimal combination of tariff and duty drawback for a given revenue level is not unique. Second, we show that if the optimal import tariff rates are all positive when the duty drawback rate is zero, then the optimal import tariff rates are always positive when the duty drawback is positive.展开更多

With the fast developing pace of the situation and the increasing requirements for undergraduates＇ English level, the available Syllabus is obviously far from satisfaction. This paper, from six perspectives, expounds the inadequacies and drawbacks of the Syllabus. It points out that college English teaching and the Syllabus need reform and should keep pace with the times.展开更多
