The Zambian mining industry is crucial to the national economy but struggles with inconsistent equipment maintenance practices. This study developed an Equipment Maintenance Management Framework (EMMF) tailored to the industry’s needs. Using surveys, interviews, and on-site visits at eight major mining companies, we identified significant variations in maintenance strategies, CMMS usage, and reliability engineering. The EMMF prioritizes predictive maintenance, efficient CMMS implementation, ongoing training, and robust reliability engineering to shift from reactive to proactive maintenance. We recommend adopting continuous improvement practices and data-driven decision-making based on performance metrics, with a phased EMMF implementation aligning maintenance with strategic business objectives. This framework is poised to enhance operational efficiency, equipment reliability, and safety, fostering sustainable growth in the Zambian mining sector. 展开更多

In recent years, China has been frequented by floods and droughts which has greatly evoked much concern from the Central Government about rural water conservancy construction. Irrigation is closely related to the "three rural" issues and concerns about the vital interests of farmers. To achieve a virtuous circle of agricultural water supply, it is necessary and urgent to establish Farmer Water User Association (FWUA) to participate in the construction, management and maintenance of small-scale irrigation system. Based on the survey on nationwide "Small-scale irrigation conditions", the roles of FWUA in the construction, management and maintenance of small-scale water conservancy have studied in this study. 展开更多

The major problem of rural water conservancy facilities during its management and maintenance is in the "been used, under no control" state. And the main reasons of this state are the public belonging property, investment by a single subject, and lack of effective supervision and management mechanism. Since rural water conservancy facilities is used in small scale and has the features of rural "acquaintances community", a balanced long-term interest mechanism for the management and maintenance of rural water conservancy facilities is established for interest-related parties. On short-term view, the most effective measure is to bring the operational status of rural water conservancy facilities into the evaluation indicators of the local government. 展开更多

Over the years, it appeared that firms failed to subject short-term investments to proper management thereby leading to either excessive or inadequate working capital which in turn affected their profitability. To empirically satisfy this, this paper examined working capital management and firms’ profitability in Nigeria quoted firms on Nigerian Stock Exchange (NSE). A panel data methodology was used with different regression estimators to analyze this relationship based on a balanced panel of 10 listed firms during the period 2008-2017. It was discovered that cash collection period and cash payment period exerted a negative impact on return on assets, though the impact was only significant for cash payment period on the ground of &#8722;0.064 (p = 0.000 &#8722;0.032 (p = 0.077 > 0.05). Also discovered was that both the current ratio and inventory period exerted a positive impact on return on assets, though the impact was only significant for current ratio on the ground of 8.172 (p = 0.000 0.05). The study concluded that working capital management affected firms’ profitability in Nigeria. Therefore it was recommended that while the shorter collection was maintained, payment to creditors should not be elongated so as to enjoy cash discount (if any) and that firms should be proactive in the management of raw materials in order to avoid idle resources that might negatively impact their financial performance. 展开更多

Efficient working capital management is an integral component of the overall corporate strategy to create shareholders' wealth. This paper seeks to extend findings regarding the relationship between working capital management and profitability. A sample of 69 companies listed on the Johannesburg Stock Exchange (JSE) for the period from 1998 to 2008 was selected. The results revealed a statistically significant negative relationship among profitability (as measured through gross operating profit), the cash conversion cycle (CCC), and number of days accounts receivable (AR). The results also revealed a positive and significant relationship among profitability, the number of days accounts payable (AP), and the number of days inventory (INV). The results suggested that managers could increase their company's profitability by effectively managing the CCC and its components. 展开更多

With the advancement of technology, companies are increasingly dependent on technology teams to stay competitive. However, members of these teams often work in stressful and unhealthy environments, which can undermine their productivity and well-being. The humanization of the culture of technology teams is an approach that aims to create healthier and more productive work environments for team members, promoting balance between personal and professional life. Despite the importance of a healthy and productive work environment, many companies do not invest in strategies to humanize the culture of their technology teams. This can lead to high levels of stress, staff turnover and low productivity. The objective of this project is to identify effective strategies to humanize the culture of technology teams and create healthier and more productive work environments in digital companies. For this, factors such as management styles, psychological safety, human-centered development, individual beliefs and time and energy management will be analyzed. The project’s methodology will include a literature review on the subject and qualitative data analysis will be performed using a content analysis approach. This project will contribute to the advancement of knowledge about the humanization of the culture of technology teams in digital companies. The results can be applied to companies that want to create healthier and more productive work environments for their team members. 展开更多
