alright pal, but there's a problem that once move the mouse over them the default color grey and does not change at all, any solution?
ASSISTANT
If the default color of the nodes is grey and it is not changing when you hover over them, it is possible that the `originalColor` property is not being set correctly for the nodes in your graph data.

Make sure that when you initialize your graph with node data, you are also setting the `originalColor` property for each node. Here's an example of how you can set the `originalColor` property when creating the graph:

```javascript
var nodes = [
    { id: 'node1', label: 'Node 1', originalColor: '#36648B' },
    { id: 'node2', label: 'Node 2', originalColor: '#36648B' },
    // more nodes...
];

var edges = [
    { id: 'edge1', source: 'node1', target: 'node2', originalColor: '#999999' },
    // more edges...
];

s.graph.clear();
s.graph.read({
    nodes: nodes,
    edges: edges
});
```

In this example, each node in the `nodes` array has an `originalColor` property set to `'#36648B'`, which is a blue color. Similarly, each edge in the `edges` array has an `originalColor` property set to `'#999999'`, which is a gray color.

Ensure that you are setting the `originalColor` property correctly for each node when creating the graph, and then the hover functionality should work as expected with the provided code.

If you already have the `originalColor` property set correctly, please double-check that it is being accessed correctly in the color assignments within the `overNode` and `outNode` functions.

Literature Review: Leadership and Leadership Styles in Agricultural Inputs Supply Chain: Assessment and Impact on the Post-COVID-19 Era in Ethiopia

Introduction:

The COVID-19 pandemic has had a profound impact on global supply chains, including those in the agricultural sector. This crisis has highlighted the importance of effective leadership and leadership styles in managing supply chains for agricultural inputs. In Ethiopia, where agriculture plays a significant role in the economy, understanding the role of leadership in the agricultural inputs supply chain is crucial for building resilience and ensuring sustainable growth. This literature review examines existing research on leadership and leadership styles in agricultural inputs supply chain management, with a specific focus on their assessment and impact on the post-COVID-19 era in Ethiopia.

1. Leadership in Supply Chain Management:

Leadership in supply chain management has been recognized as a critical factor in achieving sustainable and efficient operations. The role of effective leadership in coordinating and optimizing the flow of agricultural inputs throughout the supply chain has been emphasized in various studies. For example, Lambert et al. (2008) argue that effective leadership is essential for setting supply chain goals, aligning the interests of different stakeholders, and fostering collaboration. Leadership in supply chain management involves not only strategic decision-making but also the ability to inspire and motivate employees and stakeholders (Du et al., 2018).

2. Leadership Styles in Agricultural Inputs Supply Chain:

Different leadership styles have been identified and studied in the context of supply chain management. Transformational leadership, characterized by inspiring and motivating followers, has been found to positively impact performance and innovation in supply chains (Zhu et al., 2018). Transactional leadership, on the other hand, focuses on the exchange relationship between leaders and followers, providing rewards and punishments based on performance (Brewer & Venaik, 2011). Situational leadership, contingency leadership, and servant leadership are other leadership styles that have been explored in the supply chain context.

3. Impact of COVID-19 on Agricultural Inputs Supply Chain:

The COVID-19 pandemic significantly disrupted global and national supply chains, including those in the agricultural sector. In Ethiopia, disruptions in transportation, trade restrictions, and restrictions on movement have impacted the availability and distribution of agricultural inputs. The pandemic has also highlighted the vulnerabilities and gaps in the agricultural inputs supply chain, necessitating the need for effective leadership to navigate the challenges and build resilience (FAO, 2020).

4. Assessing Leadership in the Agricultural Inputs Supply Chain in Ethiopia:

Few studies have specifically examined leadership in the agricultural inputs supply chain in Ethiopia. However, research conducted in other countries can provide valuable insights. For instance, a study by Gligor et al. (2013) on leadership in the agricultural supply chain in the United States found that transactional leadership was associated with operational efficiency, while transformational leadership enhanced coordination and collaboration among stakeholders. Similar studies in other agricultural contexts can help inform the assessment of leadership in the Ethiopian context.

5. Building Resilience in the Post-COVID-19 Era:

The post-COVID-19 era presents an opportunity for leaders in the agricultural inputs supply chain in Ethiopia to build resilience and adapt to the new normal. This requires a reassessment of leadership styles and practices. A study by Mallqui-Bonnet et al. (2020) on the impact of COVID-19 on the agri-food supply chain in Peru highlights the need for adaptive leadership that can respond to unexpected disruptions and foster innovation. Developing leadership competencies such as strategic thinking, agility, and risk management will be crucial in navigating the challenges of the post-COVID-19 era.

Conclusion:

There is a growing recognition of the critical role of leadership and leadership styles in managing supply chains, including the agricultural inputs supply chain. While limited research specifically focuses on leadership in the agricultural inputs supply chain in Ethiopia, studies conducted in other contexts provide valuable insights. The COVID-19 pandemic has underscored the need for effective leadership in navigating disruptions and building resilience. The post-COVID-19 era presents an opportunity for leaders to reassess their styles and practices and adapt to the new normal. To further advance knowledge in this area, future research should specifically assess leadership and leadership styles in the agricultural inputs supply chain in Ethiopia and evaluate their impact on post-COVID-19 outcomes.
