The purpose of this article is to propose a detailed methodology to estimate, model and incorporate the non-constant volatility onto a numerical tree scheme, to evaluate a real option, using a quadrinomial multiplicative recombination.

This article uses the multiplicative quadrinomial tree numerical method with non-constant volatility, based on stochastic differential equations of the GARCH-diffusion type to value real options when the volatility is stochastic.

Findings showed that in the proposed method with volatility tends to zero, the multiplicative binomial traditional method is a particular case, and results are comparable between these methodologies, as well as to the exact solution offered by the Black–Scholes model.

The originality of this paper lies in try to model the implicit (conditional) market volatility to assess, based on that, a real option using a quadrinomial tree, including into this valuation the stochastic volatility of the underlying asset. The main contribution is the formal derivation of a risk-neutral valuation as well as the market risk premium associated with volatility, verifying this condition via numerical test on simulated and real data, showing that our proposal is consistent with Black and Scholes formula and multiplicative binomial trees method.

Research on college student leadership is evolving, with more scholars studying the influence of social identities on the development of student leaders. The evolving literature includes research on how race influences the leadership identity development of college students, which can support their retention and graduation from postsecondary institutions. Gaps exist in the literature on how the definitions of leaders and leadership influences leadership identity development for many social identities in numerous institutional contexts, including for Latino men. Using a case study methodology, we studied the how definitions of leaders and leadership influenced the leadership identity development of Latino men and how that influenced their placement in the LID model (Komives et al., 2005). Thirteen Latino men in the Southeastern U.S. were interviewed. Participants’ definitions and perspectives of leaders and leadership placed them all in the Leader Identified stage of the LID model. Implications for leadership educators regarding practice and research are provided.

The purpose of this study is to chart the development of Makerspaces in higher education (MIHE), by building a map of existing research work in the field. Based on a corpus of 183 manuscripts, published between January 2014 and April 2021, it sets out to describe the range of topics covered under the umbrella of MIHE and provide a holistic view of the field.

The approach adopted in this research includes development of the 2014–2021 MIHE corpus; literature overview and initial coding scheme development; refinement of the initial coding scheme with the help of a focus group and construction of the MIHE map version 1.0; refinement of the MIHE map version 1.0 following a systematic approach of content analysis and development of the MIHE map version 2.0; evaluation of the proposed structure and inclusiveness of all categories in the MIHE map version 2.0 using card-sorting technique; and, finally, development of the MIHE map version 3.0.

The research trends in the categories of the MIHE map are discussed, as well as possible future directions in the field.

This paper provides a holistic view of the field of MIHE guiding both junior MIHE researchers to place themselves in the field, and policymakers and decision-makers who attempt to evaluate the current and future scholar activity in the field. Finally, it caters for more experienced researchers to focus on certain underinvestigated domains.

The purpose of this paper is to obtain new empirical evidence about the connections between equity trading activity and five possible liquidity determinants: market capitalisation, dividend yield, earnings yield, company growth and the distinction between recently listed firms as opposed to more established ones.

The authors use a sample of 172 stocks from four European markets and estimate models using the entire sample data and different sub-samples to check the relative importance of the above determinants. The authors also conduct a factor analysis to re-classify the variables into a more succinct framework.

The evidence suggests that market capitalisation is the most important trading activity determinant, and the number of years listed ranks thereafter.

The positive relation between trading activity and market capitalisation is in line with prior literature, while the findings relating to the other determinants offer further empirical evidence which is a worthy addition in view of the contradictory results in prior research.

This study is of relevance to practitioners who would like to understand the cross-sectional variation in stock liquidity at a more detailed level.

The originality of the paper rests on two important grounds: the authors focus on trading turnover rather than on other liquidity proxies, since the former is accepted as an important determinant of the liquidity-generation process, and the authors adopt a rigorous approach towards checking the robustness of the results by considering various sub-sample configurations.

This integrated care study seeks to highlight how voluntary sector “wellbeing co-ordinators” co-located in a horizontally and vertically integrated, multidisciplinary community hub within one locality of an Integrated Care Organisation contribute to complex, person-centred, co-ordinated care.

This is a naturalistic, mixed method and mixed data study. It is complementing a before-and-after study with a sub-group analysis of people receiving input from the wider hub (including Wellbeing Co-ordination and Enhanced Intermediate Care), qualitative case studies, interviews, and observations co-produced with embedded researchers-in-residence.

The cross-case analysis uses trajectories and outcome patterns across six client groups to illustrate the bio-psycho-social complexity of each group across the life course, corresponding with the range of inputs offered by the hub.

To consider the effectiveness and mechanisms of complex system-wide interventions operating at horizontal and vertical interfaces and researching this applying co-produced, embedded, naturalistic and mixed methods approaches.

How a bio-psycho-social approach by a wellbeing co-ordinator can contribute to improved person reported outcomes from a range of preventive, rehabilitation, palliative care and bereavement services in the community.

To combine knowledge about individuals held in the community to align the respective inputs, and expectations about outcomes while considering networked pathways based on functional status, above diagnostic pathways, and along a life-continuum.

The hub as a whole seems to (1) Enhance engagement through relationship, trust and activation, (2) Exchanging knowledge to co-create a shared bio-psycho-social understanding of each individual’s situation and goals, (3) Personalising care planning by utilising the range of available resources to ensure needs are met, and (4) Enhancing co-ordination and ongoing care through multi-disciplinary working between practitioners, across teams and sectors.

This study investigates the communication behavior of public health organizations on Twitter during the COVID-19 vaccination campaign in Brazil. It contributes to the understanding of the organizational framing of health communication by showcasing several instances of framing devices that borrow from (Brazilian) internet culture. The investigation of this case extends the knowledge by providing a rich description of the organizational framing of health communication to combat misinformation in a politically charged environment.

The authors collected a Twitter dataset of 77,527 tweets and analyzed a purposeful subsample of 536 tweets that contained information provided by Brazilian public health organizations about COVID-19 vaccination campaigns. The data analysis was carried out quantitatively and qualitatively by combining social media analytics techniques and frame analysis.

The analysis showed that Brazilian health organizations used several framing devices that have been identified by previous literature such as hashtags, links, emojis or images. However, the analysis also unearthed hitherto unknown visual framing devices for misinformation prevention and debunking that borrow from internet culture such as “infographics,” “pop culture references” and “internet-native symbolism.”

First, the identification of framing devices relating to internet culture add to our understanding of the so far little addressed framing of misinformation combat messages. The case of Brazilian health organizations provides a novel perspective to knowledge by offering a notion of internet-native symbols (e.g. humor, memes) and popular culture references for misinformation combat, including misinformation prevention. Second, this study introduces a frontier of political contextualization to misinformation research that does not relate to the partisanship of the spreaders but that relates to the political dilemmas of public organizations with a commitment to provide accurate information to citizens.

The findings inform decision-makers and public health organizations about framing devices that are tailored to internet-native audiences and can guide strategies to carry out information campaigns in misinformation-laden social media environments.

The findings of this case study expose the often-overlooked cultural peculiarities of framing information campaigns on social media. The report of this study from a country in the Global South helps to contrast several assumptions and strategies that are prevalent in (health) discourses in Western societies and scholarship.

This study uncovers unconventional and barely addressed framing devices of health organizations operating in Brazil, which provides a novel perspective to the body of research on misinformation. It contributes to existing knowledge about frame analysis and broadens the understanding of frame devices borrowing from internet culture. It is a call for a frontier in misinformation research that deals with internet culture as part of organizational strategies for successful misinformation combat.

This paper aims to examine the interconnection between marketing and entrepreneurship among small and medium scale enterprises in emerging markets.

Quantitative data were obtained from 113 micro, small and medium scale enterprises (SME) into services, manufacturing and agriculture selected conveniently within the Tema metropolis, a harbour city in Ghana; however, purposive sampling was used to choose owners and managers as respondents pre-occupied with marketing and entrepreneurial roles. These voluntary informants have operated between 4 and 9 years.

The study reveals a significant relationship between five dimensions of the study including market orientation and entrepreneurial success; customer orientation and entrepreneurial success; competitor orientation and entrepreneurial success; intelligence generation; and entrepreneurial success, including information dissemination and entrepreneurial success.

Blending marketing with entrepreneurial initiatives has the propensity to accelerate success for wealth and job creation for national development especially in emerging markets where poverty and under development abounds. Adoption of basic marketing principles enables local entrepreneurs to become vehicles for social re-engineering and for rapid socio-economic growth, which ultimately affects lives at the local level. The study was limited to opinion of SME managers and owners of a harbour city.

Application of basic marketing principles influences entrepreneurial success in emerging markets (EMs) highlighting opinions of managers and owners of SMEs strategy warranting attention of stakeholders. Thus, the study validates theoretical model of how prudent marketing and entrepreneurial attitude contributes entrepreneurial success. It also provides a new perspective on marketing principles and success in emerging markets.

Consciously incorporating basic marketing principles into operations of MSMEs will impact performances; hence, social lives of entrepreneurs will be affected positively.

This study being among the few in sub-Saharan Africa highlights how application of marketing principles to entrepreneurial operations is a vital role in growing local MSMEs unto the world stage. Therefore, blending basic marketing principles with entrepreneurial initiatives will accelerate wealth and job creation and national development to achieve the world's sustainable development goals aimed at reducing poverty.

This paper aims to examine the interacting effect of market dynamism and strategic planning on the performance of small- and medium-scale enterprises (SMEs) in Ghana.

This study has used quantitative approach in dealing with the interacting effect of market dynamic on strategic planning and SMEs’ performance in Ghana. Purposive sampling is used to select 200 small- and medium-sized manufacturing and service firms in Ghana. The hierarchical multiple regression analysis is performed to test the hypotheses.

This study finds that a consistent application of strategic planning methodologies contributes to the advancement of SME performance in Ghana. In addition, it was ascertained that market dynamism has a significant positive relationship with firm performance, although its effect is not significant. Finally, the study reveals that market dynamism only influences SME performance when there is strategic planning.

The findings are limited to the SMEs in Ghana. The study of market dynamism, strategic planning and performance is a very complex activity; therefore, to gather rich data on such research work may be best accomplished if the researchers adopt mixed method data gathering techniques. This will enrich the understanding on market dynamism, strategic planning and SMEs’ performance relationship.

The findings of this research work offer guidance to owners or managers considering how to develop market dynamics and strategic planning to enhance firm performance.

This study reports on an obvious gap in the prevailing literature that few empirical research works have explored on the possible impacts of market dynamism and strategic planning on performance of SMEs in a third world country.

This study investigates theoretical relationships among personality characteristics, preferences for different types of rewards and the propensity to choose a job in auditing by management-related higher education students. Specifically, the authors consider motivation, locus of control (internal and external) and self-efficacy (SE) as personality characteristics and financial, extrinsic, support and intrinsic as types of rewards.

Data were collected through a questionnaire targeted at management-related higher education students in Portugal. Partial least squares structural equation modelling was used to analyse the data.

The full sample results show that different types of motivation, locus of control and SE are related to different reward preferences. The authors also find a positive association between a preference for extrinsic rewards and the propensity to choose a job in auditing. Moreover, when the authors consider the role of working experience in the model, the authors find that the reward preferences that drive the choice of an auditing job differ according to that experience.

This study enriches the literature by assessing preferences for different types of rewards, considering multiple personality characteristics and a comprehensive set of rewards. Furthermore, the authors identify the reward preferences that drive the choice of an auditing career. This knowledge empowers auditing firms to devise recruitment strategies that resonate with candidates’ preferences, which boosts the capacity of these companies to attract new auditors.
