2020 年第一季度，波兰经济表现相对坚韧，主要原因是其受重创行业的敞口较小，且经济多元化。
预计 GDP 将在第二季度暴跌，此后将逐步恢复，2020 年 GDP 年增长率将达到 -4½% 左右，2021 年将达到 4¼%。尽管政府采取了措施，但由于消费者积累了预防性储蓄，并因社交距离和高度不确定性而抑制支出，私人消费在 2020 年可能会受到影响。再加上供应链中断和 3 月和 4 月订单下降，企业信心低迷可能会对投资产生影响，预计投资将在第二季度暴跌，并在预测期内仅部分恢复。此外，波兰主要贸易伙伴的需求下降可能会对 2020 年的出口造成影响，尤其是在运输和旅游业。由于预计进口下降幅度较小，贸易平衡将拖累 2020 年的增长。

DoubleLine 战略商品基金概况介绍
Sector allocations and Fund holdings are subject to change at any time and should not be considered a recommendation to buy or sell any security. Portfolio holdings generally are made available 30 days after month-end by visiting www.doubleline.com. The source for the information in this report is DoubleLine Capital, which maintains its data on a trade date basis. Risk Disclosure Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. The Fund invests in foreign securities which involve greater volatility and political, economic and currency risks and differences in accounting methods. These risks are greater for investments in emerging markets. The Fund may use leverage which may cause the effect of an increase or decrease in the value of the portfolio securities to be magnified and the Fund to be more volatile than if leverage was not used. Derivatives involve special risks including correlation, counterparty, liquidity, operational, accounting and tax risks. These risks, in certain cases, may be greater than the risks presented by more traditional investments. Investing in ETFs and ETNs involve additional risks such as the market price of the shares may trade at a discount to its net asset value ("NAV"), an active secondary trading market may not develop or be maintained, or trading may be halted by the exchange in which they trade, which may impact a Funds ability to sell its shares. The fund may make short sales of securities, which involves the risk that losses may exceed the original amount invested. Investments in commodities or commodity-related instruments may subject the Fund to greater risks and volatility as commodity prices may be influenced by a variety of factors including unfavorable weather, environmental factors, and changes in government regulations. Any index used by the Fund may not be widely used and information regarding its components and/or its methodology may not generally be known to industry participants, it may be more difficult for the Fund to find willing counterparties to engage in total or excess return swaps or other derivative instruments based on the return of the index. The Fund is non- diversified meaning it may concentrate its assets in fewer individual holdings than a diversified fund. Therefore, the Fund is more exposed to individual stock volatility than a diversified fund.

摘要：本研究评估了现代多元化大学环境中人工智能和人工智能相关技术在本科生日常教育活动中的有效性。参与者是13名参加马来西亚为期两周流动计划的印度尼西亚本科生。使用在现有文献和ChatGPT的帮助下设计的调查问卷来收集数据，该问卷包括十（10）个结构化项目和七（7）个开放式问题。使用相关的SPSS测试对数据进行分析。根据结果，在所有13名参与者中，有12人（92.3％）已经在日常教育活动中体验过人工智能，对人工智能的态度与人工智能体验之间以及对人工智能的态度与人工智能对教育属性的影响之间存在很强的正相关性，相关分数分别为.663和.833。根据参与者对定性问题的回答，大多数人认为人工智能和人工智能技术（例如 ChatGPT）有助于日常教育活动，帮助他们不受时间和空间限制地获取信息并快速完成与大学相关的作业。根据结果，人工智能和人工智能相关技术可以改变现代教育的不同方面。
