An isolate ofPenicillium bilaii previously reported to solubilize mineral phosphates and enhance plant uptake of phosphate was studied. Using agar media with calcium phosphate and the pH indicator alizarin red S, the influence of the medium composition on phosphate solubility and medium acidification was recorded. The major acidic metabolites produced by P. bilaii in a sucrose nitrate liquid medium were found to be oxalic acid and citric acid. Citric acid production was promoted under nitrogen-limited conditions, while oxalic acid production was promoted under carbon-limited conditions. Citric acid was produced in both growth and stationary phases, but oxalic acid production occurred only in stationary phase. When submerged cultures which normally produce acid were induced to sporulate, the culture medium shifted toward alkaline rather than acid reaction with growth.

The Covid-19 pandemic has severely tested the leadership and communication abilities of political leaders globally. Guiding an effective response to the global pandemic has required leaders to demonstrate not only effective planning and coordination skills, but the ability to communicate clear consistent messages in an empathetic manner as well. In New Zealand the first confirmed case of Covid-19 was recorded on February 28 and over the course of March and April 2020, 1,132 further cases of Covid-19 were confirmed and 19 deaths -a much lower transmission rate than most industrialized nations. On 27 April 2020, New Zealand Prime Minister Jacinda Ardern announced that they had won the battle against community transmission of Covid-19. This paper analyses the speeches and public statements (n = 40) made by Prime Minister Ardern in March and April 2020 through the lens of crisis leadership and crisis communication. In particular, it looks at the use of different mediums (parliamentary statements, daily briefings, Facebook Live broadcasts and podcasts) as mechanisms for engaging in narrative and dialogue with the public. The paper underscores the importance of communication in crisis management and looks at how positive and consistent messaging inspires confidence and social solidarity.

Small family firms have many unique relational qualities with implications for how knowledge is passed between individuals. Extant literature posits leadership approach as important in explaining differences in knowledge sharing climate from one firm to another. This study investigates how leadership approaches interact with family influence to inform perceptions of knowledge sharing. We utilise survey data (n = 110) from owner-managers of knowledge-intensive small family firms in Scotland. Our findings present a choice in leadership intention, contrasting organisation-focused participation against family-influenced guidance. Insight is offered on the implications of this leadership choice at both organisational and familial level.

Purpose Knowledge transfer plays a key role in the succession process. While much attention has been given to the passing of business knowledge form incumbent to successor, less is known about the use of nonfamily knowledge during this most crucial of family business events. The purpose of this paper is to look how knowledge from nonfamily employees is treated at times of succession. Importantly, it considers how the controlling family’s cultural background may influence nonfamily knowledge use, and subsequent implications for the succession process. Design/methodology/approach An exploratory comparative case study design is adopted in order to uncover the complex social and cultural dynamics around knowledge use. Four case studies are presented from family businesses of different, and contrasting, cultural origins. Data were collected using semi-structured interviews, observations and formal secondary data from the organisations, all of whom operate in the UK. Findings Findings reveal a complex picture, part influenced by the cultural dynamics of the family and part by business necessity. Specifically, power–distance appears as an informative cultural dimension, influencing how knowledge is used and nonfamily are perceived. While some family businesses privilege the knowledge from family, others see the need to build knowledge relationships more broadly. Originality/value This paper provides further evidence to the heterogeneity of family businesses. It moves beyond a processual explanation of succession to develop a more contextually aware understanding of the dynamics and sensitivities involved.

Our understanding of craft brewing is beginning to grow and a key theme to emerge from this artistic and intrinsically creative sector is the dependence on collaboration between entrepreneurial agents. In the North East of Scotland, the growth in craft beer is also recognised to come from a deep rooted collaboration, as a reaction to and in resistance of large mainstream competition. However, one such enterprise, BrewDog, has grown to achieve global reach to rival that of the large-scale brewers the craft scene sought to challenge. We consider what this unprecedented success means for the remaining collaborators in the local craft beer sector. Our findings point to a shared optimism and possibility of achievement among the craft brewers, aided by BrewDog’s success. However, the nature of collaboration is anchored more in community embeddedness and shared responsibility for market development, rather than in business growth and success replication. While the craft scene acknowledges the inspirational success of ‘one of their own’, strategic drive comes from more localised relations and a desire for independence. This has implications not only for craft beer but also on how collaboration among entrepreneurs sustains in respond to success from within the group.

The Electronic Health Records for Clinical Research (EHR4CR) project aims to develop services and technology for the leverage reuse of Electronic Health Records with the purpose of improving the efficiency of clinical research processes. A pilot program was implemented to generate evidence of the value of using the EHR4CR platform. The user acceptance of the platform is a key success factor in driving the adoption of the EHR4CR platform; thus, it was decided to evaluate the user satisfaction. In this paper, we present the results of a user satisfaction evaluation for the EHR4CR multisite patient count cohort system. This study examined the ability of testers (n = 22 and n = 16 from 5 countries) to perform three main tasks (around 20 minutes per task), after a 30-minute period of self-training. The System Usability Scale score obtained was 55.83 (SD: 15.37), indicating a moderate user satisfaction. The responses to an additional satisfaction questionnaire were positive about the design of the interface and the required procedure to design a query. Nevertheless, the most complex of the three tasks proposed in this test was rated as difficult, indicating a need to improve the system regarding complicated queries.
