The creation of positive social change (PSC) is considered the primary success criterion when evaluating social enterprise performance. However, despite a proliferation of PSC-measurements, their empirical validity and applicability in emerging economies remain largely unclear. The quantitative study examines the validity of the PSC-measurement approaches proposed by Bloom and Smith (2010; Bloom and Smith approach [BSA]) and Weaver (2020b; Weaver approach [WA]) in South Africa.

Investigating a representative sample of 347 social entrepreneurs from Gauteng and Limpopo provinces, the authors use questionnaire data to explore the factorial, convergent and discriminant validity of both PSC-measurement approaches. Statistically, this is done by applying factorial and correlation analyses.

The results yield acknowledgeable differences. BSA has a high factorial and convergent validity, while its discriminant validity remains doubtful. For WA, problems concerning factorial validity occur.

Despite limited generalizability, the authors provide a first guideline for scholars regarding the empirical validity of BSA and WA outside the context of developed economies.

The current study sheds light on the validity of two PSC-measurement approaches in an emerging economy context. This way, the authors contribute to the field by addressing the scarcity of empirical research and the restricted scope of developed economies regarding PSC-measurement.

This research study focusses on the succession challenges in small-medium outboard marine businesses of Malaysian Chinese family ownership. The founder-owners face challenges in convincing the next-generation members to establish their careers within the family business and to ensure successions are in place to safeguard the family's wealth. A gap exists in the research literatures concerning such family business owners; and their experiences would provide valuable information to other Malaysian Chinese family businesses planning to start the succession journey.

An exploratory case study methodology to research five Malaysian Chinese family businesses cases in Klang Valley, Selangor, Malaysia, is used in this study. The primary qualitative data were obtained through in-depth, semi-structured interviews and observations. The research data lead to the identification of the following themes: generational change affects the survival of small-medium Malaysian Chinese family-owned businesses; the founder-owners' intention and desire for business to pass to the next generation give rise to the imperative of succession; the founder-owners' motive and goals, family context and the business nature would determine a large part to how the succession plans are carried out and the upbringing, expectation and obligations would determine how the next generations of children would view the prospect of taking over the family business. From this, a succession model that detailed an inclusive approach to succession planning process between the two generations is established.

A small purposive sample is included, and it is recommended that a larger and more diverse sample be collected in future studies. This study follows a nuclear family structure of parents and children. If more Chinese family businesses are selected based on a wider set of family members such as uncles and cousins, the findings may differ.

This research study could also facilitate other Malaysian family businesses to rethink and refocus on the importance of undertaking an inclusive approach to succession planning and also help potential next-generation successors in understanding and working towards attaining the qualities that family firms look for in future leaders.

The researcher summarizes the study findings into a management succession model. An inclusive succession approach is needed to overcome these challenges and would enable sustainability, continuity and longevity of the family business. This would help the family business to understand that succession is not a single event but a process that needs to be planned together with the next-generation family members over a certain period of time.

The purpose of this study is to analyse and compile the literature on various option pricing models (OPM) or methodologies. The report highlights the gaps in the existing literature review and builds recommendations for potential scholars interested in the subject area.

In this study, the researchers used a systematic literature review procedure to collect data from Scopus. Bibliometric and structured network analyses were used to examine the bibliometric properties of 864 research documents.

As per the findings of the study, publication in the field has been increasing at a rate of 6% on average. This study also includes a list of the most influential and productive researchers, frequently used keywords and primary publications in this subject area. In particular, Thematic map and Sankey’s diagram for conceptual structure and for intellectual structure co-citation analysis and bibliographic coupling were used.

Based on the conclusion presented in this paper, there are several potential implications for research, practice and society.

This study provides useful insights for future research in the area of OPM in financial derivatives. Researchers can focus on impactful authors, significant work and productive countries and identify potential collaborators. The study also highlights the commonly used OPMs and emerging themes like machine learning and deep neural network models, which can inform practitioners about new developments in the field and guide the development of new models to address existing limitations.

The accurate pricing of financial derivatives has significant implications for society, as it can impact the stability of financial markets and the wider economy. The findings of this study, which identify the most commonly used OPMs and emerging themes, can help improve the accuracy of pricing and risk management in the financial derivatives sector, which can ultimately benefit society as a whole.

It is possibly the initial effort to consolidate the literature on calibration on option price by evaluating and analysing alternative OPM applied by researchers to guide future research in the right direction.
