ABSTRACT
Background: Given the limited benefits of current treatments for Parkinson’s disease (PD), inter-ventions that might provide supplementary benefits would be of value. The traditional Chinese medicine practice of Tai Chi has been said to improve some aspects of PD, particularly imbalance. Methods: Preliminary randomized, controlled, and rater-blinded clinical trial of Tai Chi, focusing on its effects on global motor, daily function, mood and quality of life. Subjects continued their standard medical therapy and were randomly assigned to Tai Chi (16 weekly classes, expert trainer, practice at home between classes) or no Tai Chi (control group) in a 2:1 ratio. The primary outcome measure was the total motor score of the Unified Parkinson’s Disease Rating Scale (UPDRS) and this was scored by an experienced rater who was blinded to the treatment assignment. The same rater scored the Schwab and England Activities of Daily Living Scale. The patient-completed Geriatric Depression Scale, PD (quality of life) Questionnaire-39, and fall diary were also analyzed. Results: 44 subjects participated with 29 assigned to Tai Chi and 15 serving as controls. Tai Chi was well-tolerated. Seven subjects withdrew prior to completion (2 from Tai Chi, 5 from control). We found no significant difference between treatment groups in the change in scores from baseline to end of intervention for any of the scales. Trends toward a benefit of Tai Chi were observed for individual UPDRS items (depression, finger tapping, hand movements, posture). Conclusions: Tai Chi does not appear to improve global measures in patients with PD. The practice may have benefits for PD, but these appear to be largely restricted to specific motor tasks and perhaps mood rather than being a global functional response. More study is needed to clarify and establish efficacy.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
