Aiming at the problem of incompatibility of biomass models of forest organs, taking Chinese fir in Fujian Jiangle State-owned Forest Farm as the research object, based on selecting the optimal independent model of each organ, the biomass compatibility model of Chinese fir was established with a three-level joint control scheme. The results show that the compatibility equation system based on the whole plant biomass can effectively solve the problem of incompatibility in the whole plant biomass, each sub-biomass and between sub-biomass. Besides, except for the leaf biomass model, all other biomass models have good fitting effect, which is of great significance to the guidance of the analysis of local Chinese fir biomass.

This research aims to build an appropriate leadership model for regional heads in mitigating disasters due to climate change that is occurring in Papua. Papua Island is one of the islands that is included in disaster-prone areas, namely earthquakes, flash floods, tidal floods and landslides. This disaster occurred due to Papua’s geological conditions in the form of activity on the Indo-Australian plate (southern part) and the Pacific plate (north-eastern part). Exploitation of nature carried out by companies and communities themselves in a particular area has an impact on the balance of the natural ecosystem. So far, disaster management has only focused on emergency response. Aid movements coordinated by ordinary people also focus more on raising aid for emergency situations. In fact, comprehensive disaster management includes before, during and after a disaster occurs. So a combination of leadership styles is needed that must be carried out at each phase of a disaster so that the right model can be produced. The results of this research found that the leadership model of regional heads in mitigating climate change in Papua is in accordance with the disaster management cycle with leadership styles, and traditional Papuan leadership styles. This combination is called a collaborative leadership model for disaster management in Papua. It is hoped that by implementing this model, climate change disaster mitigation can be effective.

Ostensibly, theories from the eastern and western worlds have emphasized different aspects of character, while in India, greater importance is attached to character building. We must understand that character building establishes surroundings for the human being with distinct values and virtues persisting inside him. This study attempts to explain the importance of the character merits of young managers in mitigating volatile, uncertain, complex, and ambiguous (VUCA) challenges encountered in a business journey. This scholarly effort, with a framework of being reflective and expressive, attempts to capture empirical and qualitative data, hence presenting a model and explaining the connection between the character of young managers and VUCA. The authors initially mine on what character implies and how it could be plausibly examined. Character, as a manifestation, is qualitatively distinguished as a sum of one’s bent of mind, embracing the brighter part of good qualities and consolidating a frame to capture the countenance of a genuine personality. We must understand that for organisation’s growth and sustainability, it is vital for the human resources department to maintain a training methodology that is systematic and focused on character building.
