Climate change and the COVID-19 pandemic are complex and have multifaceted effects on countries in an unpredictable and unprecedented manner. While both COVID-19 and the climate crisis share similarities, they also have some notable differences. Being both systemic in nature with knock-on and cascading effects that propagate due to high connectedness of countries, COVID-19, however, presents imminent and directly visible dangers, while the risks from climate change are gradual, cumulative and often distributed dangers. Climate change has more significant medium and long-term impacts which are likely to worsen over time. There is no vaccine for climate change compared to COVID-19. In addition, those most affected by extreme climatic conditions have usually contributed the least to the root causes of the crisis. This is in fact the case of island economies. The chapter thus investigates into the vulnerability and resilience of 38 Small Islands Developing States (SIDs) to both shocks. Adopting a comprehensive conceptual framework and data on various indices from the literature and global databases, we assess the COVID-19 and climate change vulnerabilities of SIDs on multiple fronts. The results first reveal a higher vulnerability across all dimensions for the Pacific islands compared to the other islands in the sample. There is also evidence of a weak correlation between climate change risk and the COVID-19 pandemic confirming our premise that there are marked differences between these two shocks and their impacts on island communities.

Customer lifetime value (CLV) is one of the key indicators to measure the success or health of an organization. How can an organization assess the organization's customers' lifetime value (LTV) and offer relevant strategies to retain prospective and profitable customers? This study offers an integrated view of different methods for calculating CLVs for both loyalty members and non-membership customers.

This study outlines eleven methods for calculating CLV considering (1) the deterministic aspect of NPV (Net present value) models in both finite and infinite timespans, (2) the geometric pattern and (3) the probabilistic aspect of parameter estimates through simulation modeling along with (4) the migration models for including “the probability that customers will return in the future” as a key input for CLV calculation.

The CLV models are validated in the context of complementary and alternative medicine (CAM)in the healthcare industry. The results show that understanding CLV can help the organization develop strategies to retain valuable customers while maintaining profit margins.

The integrated CLV models provide an overview of the mathematical estimation of LTVs depending on the nature of the customers and the business circumstances and can be applied to other business settings.

This paper aims to integrate the extant literature on the impact of positive leadership on organisational outcomes within the Australian not-for-profit (NFP) organisations, identifies existing gaps in the literature and proposes a framework capturing feasible pathways for future research on positive leadership in NFP organisations.

This is a systematic review of the existing literature on positive leadership and external/environmental factors and organisational values as applied to Australian NFP organisations mainly based on journal articles.

This paper proposes a plausible conceptual framework postulating how Australian NFP organisations could attain superior performance outcomes when there is a perfect alignment between positive forms of leadership, external/environmental factors and organisational values. We explain the conceptual framework through testable research propositions explaining interrelationships between positive leadership, external/environmental factors, organisational values and organisational performance.

The review focused on two positive forms of leadership (i.e. transformational and servant) and could benefit by including other closely related leadership styles and behaviours (like authentic and ethical leadership). In addition to the positivist paradigm and quantitative approach adopted by this paper, interpretative and critical paradigms and related qualitative approaches may also lend themselves well to exposing pertinent issues and relationships that have not been imagined before in the under-researched NFP sector.

Leaders within NFP organisations need to understand when and how to align positive forms of leadership, external/environmental factors and organisational values to maximise limited resources available to Australian NFP organisations.

This systematic review adds to the limited literature exploring the impact of positive forms of leadership within Australian NFP organisations. The proposed framework offers unique insights into the relationships between positive forms of leadership, external/environmental factors, organisational values and organisational performance.
