The purpose of this article is to provide information about interactions between pink-pigmented facultative methylotroph (PPFM) organisms and plants, their molecular mechanisms of methylotrophic metabolism, application of PPFMs in agriculture, biotechnology and bioremediation and also to explore lacuna in PPFMs research and direction for future research.

Research findings on PPFM organisms as potent plant growth promoting organisms are discussed in the light of reports published by various workers. Unexplored field of PPFM research are detected and their application as a new group of biofertilizer that also help host plants to overcome draught stress in poorly irrigated crop field is suggested.

PPFMs are used as plant growth promoters for improved crop yield, seed germination capacity, resistance against pathogens and tolerance against drought stress. Anti-oxidant and UV resistant properties of PPFM pigments protect the host plants from strong sunshine. PPFMs have excellent draught ameliorating capacity.

To meet the ever increasing world population, more and more barren, less irrigated land has to be utilized for agriculture and horticulture purpose and use of PPFM group of organisms due to their draught ameliorating properties in addition to their plant growth promoting characters will be extremely useful. PPFMs are also promising candidates for the production of various industrially and medicinally important enzymes and other value-added products. Wider application of this ecofriendly group of bacteria will reduce crop production cost thus improving economy of the farmers and will be a greener alternative of hazardous chemical fertilizers and fungicides.

This study aims to identify and compare the measurement models of earnings management (EM) appropriate to the Iranian Islamic banking system. The importance of reported profit figures has motivated business executives, who also perform financial reporting, to manipulate these figures. These measures are referred to as “earnings management,” which negatively influence the quality of reported earnings and financial statements' reliability.

In this study, four methods, namely, Jones (1991), modified Jones (Dechow et al., 1995), Kasznik (1999) and Kothari et al. (2005), were used to measure the EM index in 25 Iranian Islamic banks (IBs) registered with the Tehran Stock Exchange and/or the Central Bank of Iran. The study covered the period 2005–2020. Following the aforementioned methods, this research implemented templates that were repeatedly tested in subsequent studies using accruals to discover EM.

The results show that the Kasznik (1999) model is the preferred and compatible model with the Iranian Islamic banking system's accrual behaviour due to the consistency of the measurement coefficients with theoretical and previous research findings. Therefore, total accruals, including discretionary accruals and non-discretionary accruals, have the most correspondence with (1) property, machinery and equipment; (2) the change in cash flow from operating activities; and (3) the difference of change in revenue (ΔREV) and change in net receivable accounts (ΔREC).

This is the first investigation in the Iranian Islamic banking system. The research contributes to the Iranian Islamic banking system literature on the implements of EM, which could be appealed to in the context of developing countries like Iran. Finally, this study highlights the different EM capabilities in Islamic banking systems similar to the Iranian banking arrangement.

There is a noticeable dearth of literature offering Marxist perspectives and analyses on the Bangsamoro struggles for self-determination, ethnic and religious identities and social justice. A reason for this may lie in the general derision of bourgeois academics and conventional commentators on the supposed paucity of Marxist theories on nationalism, ethnicity and religion. This may have influenced, ironically, Filipino Marxist thinkers into being indifferent to this research topic. Far from the truth, however, that Marxism is essentially an economic determinist social conflict theory, its historical materialism offers a rich treasury of analyses and perspectives on nationalism, self-determination, religion and ethnic identity within the context of class struggles as the acme of the theory of scientific socialism. The paper, therefore, offers a scientific analysis of the Bangsamoro Question from a Marxist standpoint beyond the perspectives of psychologism, naturalism and ethno-racialism, which are usually deployed by traditional and uninformed commentators in analyzing ethnicity questions and quests for separatism.

The paper employs the historical and class analysis of the dynamics, relationships and struggles of classes in the history of the Bangsamoro struggles against colonialism and the subsequent postcolonial regimes up to the present time.

As a scientific paradigm, historical materialism presents itself as a general scientific social conflict theory. Using this framework through historical and class analyses, the paper proves the improbability of the Moros’ quest for separatism or genuine autonomy at this historical point. It, therefore, asserts the linking of the Moro struggles to the more immense struggles of the Filipinos for national and social liberation from imperialism.

The paper is limited to the historical and class analyses of classes’ dynamics and struggles. It is, therefore, far from an exhaustive analysis of the Moro struggles using different non-Marxist social conflict theories.

The research can be considered a practical guide in analyzing and predicting the trajectories of the Moro struggles in Mindanao and Sulu.

The work addresses the question from radical and Marxist premises.

This is a highly original and valuable work from the point of view of Marxist social conflict theory.
