Abstract
Purpose
The purpose of this paper is to examine the effect of the application of microorganisms of phosphate providers and organic matters for the growth of Arabica coffee seedlings in Bener Meriah Regency.
Design/methodology/approach
The experiments were performed inside the screen house using a random design of factorial group with six repetitions. The experimental treatments consisted of two factors. Factor I is the application of microorganisms of phosphate providers. Factor II is the application of organic matters (T. diversifolia and the coffee bean skins). The parameters observed were as follows: enhancement of plant height was observed every 30 days for 270 days, and a number of primary branch and dry weight of roots were observed 270 days after planting (DAP). The data obtained were analyzed by analyzing the variance at 5 per cent level; if the treatment had an effect, then the treatment was continued to Duncan’s multiple range test at 5 per cent.
Findings
The application of microorganisms of phosphate provider increases the height improvement, the number of primary branches and the dry weight of roots of Arabica coffee seedlings. The application of Listeria sp. microorganisms of phosphate provider gives the highest yield on the height increase, the number of primary branches and the dry weight of roots of Arabica coffee seedlings. The application of organic matters of coffee beans skin gives higher yield than Tithonia diversifolia in height and dry weight of roots of Arabica coffee seedlings. The interaction between the application of microorganisms of phosphate provider and organic matters increases the dry weight of roots of Arabica coffee seedlings. The interaction of Listeria sp.-skin of coffee beans gives the highest yield on dry weight of roots of Arabica coffee seedlings.
Originality/value
Several other studies have demonstrated that the application of microorganisms of phosphate providers using phosphate solubilizing bacteria (Fitriatin et al., 2014; Sembiring et al., 2017) and mycorrhizal use (Hart and Trevors, 2005; Rouphael et al., 2015) increased the growth and yield plant. No previous study comprehensively studied the application of microorganisms of phosphate providers and organic matters to improve the growth of Arabica coffee seedlings in Andisol in Bener Meriah Regency.

Abstract
Purpose
Based on the role congruity theory (RCT), this study aims to determine the effects of gender roles on life satisfaction and occupational commitment levels of female employees working in law enforcement.
Design/methodology/approach
Hypotheses were tested through a series of hierarchical regression analyses on the data collected from 394 female respondents who are having their first year in law enforcement.
Findings
Both male and female gender roles were positively related to the life satisfaction levels of women working in law enforcement. Female gender role was also positively linked to higher levels of occupational commitment. The link between male gender role and occupational commitment was nonlinear; therefore, the positive relationship between the variables turns into a negative one for higher levels of male gender role.
Originality/value
This study furthers the understanding of RCT and its implications regarding how gender roles link to work-related outcomes, especially for women working in a male-dominated work context.

Abstract
Purpose
This research aims to comprehend the factors that impact the emerging inclination of consumers toward mobile finance technology (fintech) services over banking institutions. The study focuses on users' demographics and psychographics to delineate their unique segments and profiles.
Design/methodology/approach
The study proposes a segmentation and profiling framework that includes variance analysis, two-step cluster analysis and pairwise statistical tests. This framework is applied to a dataset of customers using a range of mobile fintech services, specifically robo-investment, peer-to-peer (P2P) payments, robo-advisory and digital savings. The analysis creates distinct customer profile clusters, which are later validated using pairwise statistical tests based on segmentation output.
Findings
Empirical results reveal that P2P payment service users exhibit a higher frequency of usage, proficiency and intention to continue using the service compared to users of robo-investment or digital savings platforms. In contrast, individuals utilizing robo-advisory services are identified to have a significantly greater familiarity and intention to sustain engagement with the service compared to digital savings users.
Practical implications
The findings provide financial institutions, especially traditional banks with actionable insights into their customer base. This information enables them to identify specific customer needs and preferences, thereby allowing them to tailor products and services accordingly. Ultimately, this understanding may strategically position traditional banks to maintain competitiveness amidst the increasing prominence of fintech enterprises.
Originality/value
This research provides an in-depth examination of customer segments and profiles within the mobile fintech services sphere, thus giving a nuanced understanding of customer behavior and preferences and generating practical recommendations for banks and other financial institutions. This study thereby sets the stage for further research and paves the way for developing personalized products and services in the evolving fintech landscape.

Abstract
Purpose
With the objective to assess potentially performant hybrid-electric architectures, this paper aims to present an aircraft performance level evaluation, in terms of range and payload, of the synergies between a hybrid-electric energy system configuration and a cryogenic fuel system.
Design/methodology/approach
An unmanned aerial vehicle (UAV) is modeled using an aircraft performance tool, modified to take into account the hybrid nature of the system. The fuel and thermal management systems are modeled looking to maximize the synergistic effects. The electrical system is defined in series with the thermal engine and the performance, in terms of weight and efficiency, are tracked as a function of the cooling temperature.
Findings
The results show up to a 46 per cent increase in range and up to 7 per cent gain on a payload with a reference hybrid-electric aircraft that uses conventional drop-in JP-8 fuel. The configuration that privileges a reduction in mass of the electric motors by taking advantage of the cryogenic coolant temperature shows the highest benefits. A sensitivity study is also presented showing the dependency on the modeling capabilities.
Practical implications
The synergistic combination of a cryogenic fuel and the additional heat sources of a hybrid-electric system with a tendency to higher electric component efficiency or reduced weight results in a considerable performance increase in terms of both range and payload.
Originality/value
The potential synergies between a cryogenic fuel and the electrical system of a hybrid-electric aircraft seem clear; however, at the present, no detailed performance evaluation at aircraft level that includes the fuel, thermal management and electric systems, has been published.

Abstract
Purposes
This study paper aims to analyse a real life case based on Human Resource Management, specifically the concepts of the recruitment process and the grapevine.
Theoretical basis
The main topic is HRM related. Concepts introduced include recruitment process and grapevine.
Research methodology
The information for the case was attained from one-on-one interviews with the main case protagonist, Sabrina (name of all characters in the case and organisations have been changed as per request of the interviewee. However, all the happenings in the case are real).
Case overview/synopsis
This case deals with the tricky situation faced by Sabrina, an certain employee of an international development organisation, (an institution focussing on aiding development in economically underdeveloped countries), who finds herself in when she inadvertently comes across some negative information about a job candidate currently in the middle of the recruitment process, who, if successful, will become her colleague and work closely with her in future. It has taken months to find this candidate, and if hired should lighten Sabrina’s workload tremendously. The preliminary decision maker in the case is Sabrina, but the ultimate management decision will have to be made by her boss John Nash.
Complexity academic level
The case can be used at undergraduate and graduate level. The main topic is Human Resource Management (HRM) related. It is of preliminary level of difficulty. There are no specific prerequisites. Concepts introduced include recruitment process and grapevine.

Abstract
Purpose
The sluggish progression of disaster-induced housing reconstruction (DHR) in Sri Lanka provoked the assessment of drywall technologies as a mode of improving efficiency. The purpose of this paper is to investigate the applicability of drywall technologies to adopt a technical solution to DHR.
Design/methodology/approach
The research contextualized a mixed research design via a case-study strategy integrating semi-structured interviews, documentary reviews and observations. Two cases based on the 2016 Samasarakanda landslide were investigated. Within-case-analysis and cross-case-analysis were performed to derive conclusions.
Findings
Enablers for drywall technologies application are time saving, cost-saving, less water consumption and logistical easiness. Less strength of drywall technologies will not be a critical obstruction owing to the expected disaster resilience from the concrete frame and the subsequent requirement of non-load bearing walls for landslide DHR. Labor source, community acceptance, durability are potential settings of barriers. Observing model houses, researching the resistance of drywall technologies to landslide-induced vibrations and impulsive waves are some further research areas discovered.
Research limitations/implications
Empirical findings are centered on the 2016 Samasarakanda DHR.
Practical implications
Because of many issues in updating guidelines, drawings and BOQs, a protocol should be gazetted in the parliament to improve its updating flexibility allowing provisions to apply novel technologies for DHR.
Originality/value
Being one of the very first of this kind of research, contextually, the research is original. This study provokes insightful investigation of drywall technologies for DHR beyond its overlooked properties. This study reveals many wall construction challenges of the 2016 Samasarakanda DHR which have not yet been explored in research.

Abstract
Purpose
The purpose of this paper is to introduce a generalization of the time-varying correlation elliptical copula models and to analyse its impact on the tail risk of a portfolio of foreign currencies during the Covid-19 pandemic.
Design/methodology/approach
The authors consider a multivariate time series model where marginal dynamics are driven by an autoregressive moving average (ARMA)–Glosten-Jagannathan-Runkle–generalized autoregressive conditional heteroscedastic (GARCH) model, and the dependence structure among the residuals is given by an elliptical copula function. The correlation coefficient follows an autoregressive equation where the autoregressive coefficient is a function of the past values of the correlation. The model is applied to a portfolio of a couple of exchange rates, specifically US dollar–Japanese Yen and US dollar–Euro and compared with two alternative specifications of the correlation coefficient: constant and with autoregressive dynamics.
Findings
The use of the new model results in a more conservative evaluation of the tail risk of the portfolio measured by the value-at-risk and the expected shortfall suggesting a more prudential capital allocation policy.
Originality/value
The main contribution of the paper consists in the introduction of a time-varying correlation model where the past values of the correlation coefficient impact on the autoregressive structure.

Abstract
Purpose – In this chapter, we explore how normalization of exclusionary practices and of privilege for seemingly same professionals and disadvantage for seemingly different professionals in academic healthcare organizations can be challenged via meaningful culturalization in the interference zone between system and life world, subsequently developing space for belonging and difference.
Methodology – This nested case study focusses on professionals’ narratives from one specific setting (team) within the broader research and research field of the Dutch academic hospital (Abma & Stake, 2014). We followed a responsive design, conducting interviews with cultural minority and majority professionals and recording participant observations.
Findings – In the Netherlands, the instrumental, system-inspired business model of diversity is reflected in two discourses in academic hospitals: first, an ideology of equality as sameness, and second, professionalism as neutral, rational, impersonal and decontextual. Due to these discourses, cultural minority professionals can be identified as ‘different’ and evaluated as less professional than cultural majority, or seemingly ‘same’, professionals. Furthermore, life world values of trust and connectedness, and professionals’ emotions and social contexts are devalued, and professionals’ desire to belong comes under pressure.
Value – Diversity management from a system-based logic can never be successful. Instead, system norms of productivity and efficiency need to be reconnected to life world values of connectivity, personal recognition, embodied knowledge and taking time to reflect. Working towards alternative safe spaces that generate transformative meaningful culturalization and may enable structural inclusion of minority professionals further entails critical reflexivity on power dynamics and sameness–difference hierarchy in the academic hospital.
