Authors: Aslam Javed , Saleem Aqeela , Kim Yun Bae 
Published: June 2023

PurposeThis study aims to proposed that blockchain helps the organization improve supply chain (SC) performance by improving integration, agility and security through real-time information sharing, end-to-end visibility, transparency, data management, immutability, irrevocable information and cyber-security platforms.Design/methodology/approachThis study has made an initial effort toward proposing a framework that shows the problems and challenges for the O&G SC under its segments (upstream, midstream and downstream) and provides the interlink among blockchain properties for SCM problems. SC managers were selected for survey questionnaires from the Pakistan O&G industries.FindingsThis study analyzes the impact of blockchain-enabled SC on firm performance with an understanding of the SC robustness capabilities as a mediator. The result revealed that the SC manager believes that the blockchain-enabled SC has a positive and significant on firm performance and robustness capabilities.Research limitations/implicationsBlockchain technology is reflected as high-tech to support the firm process, responses and methods. The technology helps eliminate bottlenecks, avoid uncertainties and improve decision-making, leading to improved SC functions. This study guides managers about the potential problems of existing SC and how blockchain solves SC problems more effectively.Originality/valueThe oil and gas (O&G) sectors are neglected by researchers, and there are limited studies on O&G supply chain management (SCM). Additionally, no empirical evidence suggests implementing blockchain for O&G as a solution for potential problems. Furthermore, present the roadmap to other industries those having complex SC networks for the implication of blockchain to improve the SC performance.
The composite approach as a hybrid approach to business process modeling: proposition and empirical evaluation
Authors: Antunes Pedro , A. Pino José , Nkhoma Mathews , Thuan Nguyen Hoang 
Published: June 2023

PurposeBusiness process modeling faces a difficult balance: on the one hand, organizations seek to enact, control and automate business processes through formal structures (procedures and rules). On the other hand, organizations also seek to embrace flexibility, change, innovation, value orientation, and dynamic capabilities, which require informal structures (unique user experiences). Addressing this difficulty, the authors propose the composite approach, which integrates formal and informal process structures. The composite approach adopts a socio-material conceptual lens, where both material and human agencies are supported.Design/methodology/approachThe study follows a design science research methodology. An innovative artifact – the composite approach – is introduced. The composite approach is evaluated in an empirical experiment.FindingsThe experimental results show that the composite approach improves model understandability and situation understandability.Research limitations/implicationsThis research explores the challenges and opportunities brought by adopting a socio-material conceptual lens to represent business processes.Originality/valueThe study contributes an innovative hybrid approach for modeling business processes, articulating coordination and contextual knowledge. The proposed approach can be used to improve model understandability and situation understandability. The study also extends the socio-material conceptual lens over process modeling with a theoretical framework integrating coordination and contextual knowledge.
Does enterprise social media use in the post-acceptance stage improve employee autonomy? An information processing perspective
Authors: Yin Pengzhen , Wang Wei , Wang Chuang , Liang Liang 
Published: June 2023

PurposeWith the prevalence of enterprise social media (ESM), this study examines how the innovative and routine ESM use behaviors in the post-acceptance stage influence the quality and quantity dimensions of information processing (i.e. information equality and information overload), subsequently affecting employee autonomy grounded in the digital information management theoretical (DIMT) framework. This study further explores the moderating effects of communication visibility on the relationships between employee autonomy and each of the two information processing factors.Design/methodology/approachThe proposed theoretical model was empirically validated using survey data of 266 knowledge workers that use ESM in a hybrid working context.FindingsThe results demonstrate that innovative and routine ESM use have different impacts on the quality and quantity dimensions of information processing, and information equality (quality dimension) improves employee autonomy as expected, but, surprisingly, information overloads (quantity dimension) as well. ESM communication visibility positively moderates the relationship between employee autonomy and each dimension of information processing.Originality/valuePrior studies on ESM use widely focused on ESM's positive and negative outcomes and the mechanisms from the perspectives of employees' psychological and cognitive reactions. How ESM use behaviors in the post-acceptance stage empower employee autonomy and allow organizations to leverage the organizations' information technology (IT) investments remains unclear. Drawing on the information processing perspective, this study provides a novel angle to examine how to leverage IT values that stem from ESM use by considering the complementary roles of active and passive information processing.
What employees perceive as personal communication: results of a Q study on internal communication
Authors: Stehle Helena 
Published: June 2023

PurposeEngaging with stakeholders in “a personal, intimate way” (Men and Tsai, 2016, p. 932) or “includ[ing] the ‘personal touch’” (Kent and Taylor, 1998, p. 323) is often seen as desirable in internal communication management. While the importance of personal communication is undisputed from the perspectives of internal communication, its communicators, and from internal stakeholders, this is not true when it comes to the dimensions and characteristics that constitute an experience of communication as feeling personal. The present study aims to explore what makes communication personal from the employees' perspective.Design/methodology/approachThe study used the Q methodology and Q method, thus focusing on an individual's subjective perspective. The Q methodology was implemented in the form of a Q-sort survey exploring the perceptions of 32 German employees (selected from a representative cross-section of 400 employees in Germany, using a balanced-block design to maximize heterogeneity).FindingsThe results show that while direct and dyadic communication is often perceived as personal, many other dimensions and characteristics are also considered “personal” in both the literature and based on stakeholder perceptions. The Q-sort survey revealed four perception types whose perceptions of communication as “personal” vary widely, with all these types rejecting non-human communicators.Originality/valueThis study contributes to the limited understanding of employees' perceptions of internal communication as “personal.” It shows how the Q methodology and Q method—a rarely used perspective—can complement existing theoretical and empirical research on internal communication. For internal communication management, the findings show that a “one-size-fits-all” approach must be questioned and that a communication team's involvement in personal communication can have negative consequences.
Monetary policy and inflation targeting under global uncertainty: a SVAR approach for Tunisia
Authors: Trabelsi Emna , Ben Khaled Asma 
Published: June 2023

Purpose
The implementation of monetary policy by the central bank is an ongoing topic of discussion. This paper aims to explore monetary policy transmission shocks in times of uncertainty using the new World uncertainty index (WUI). The authors investigate the impact of crises, wars and pandemic shocks on selected macroeconomic variables.

Design/methodology/approach
The authors use unit root tests, structural vector autoregressive model and the Granger causality test according to Toda–Yamamoto with quarterly data over 1999–2022.

Findings
The results of this study show that in the short run, there is a unidirectional relationship between the money market rate and WUI, while the relationship between the latter and the money supply (M2) is bidirectional. The short-term effect runs from WUI to inflation. In the long run, the variance decomposition shows that global uncertainty explains around 12% of inflation pressures. The uncertainty caused by special events in the world creates positive shocks on inflation in Tunisia, which decreases the ability of the central bank to control inflation.

Research limitations/implications
The results have implications over necessary and urgent actions to be implemented for a progressive economic recovery but point to a necessary transition to an inflation-targeting regime.

Originality/value
Examining monetary policy under uncertainty is a recent phenomenon. The authors purposely use a novel WUI by Ahir et al. (2022) that is unexploited in literature.
Bank risk exposures and bank stability in Africa: the role of regulations in a non-linear model
Authors: Ofori-Sasu Daniel , Mekpor Benjamin , Adu-Darko Eunice , Sarpong-Kumankoma Emmanuel 
Published: June 2023

Purpose
This paper aims to examine the interaction effect of regulations (monetary and macro-prudential) in explaining the possible non-linear effect of bank risk exposures (credit risk and insolvency risk) on banking stability in Africa.

Design/methodology/approach
The study uses a two-step system generalized method of moments (GMM) estimator for a data set of banks across 54 African countries over the period 2006–2020.

Findings
The authors find that the relationships between bank credit risk–bank stability and bank insolvency risk–bank stability are non-linear and characterized by the presence of optimal thresholds, which are 5.3456 for credit risk and 2.3643 for insolvency. Contrary to their positive effects below these optimal thresholds, credit risk and insolvency risk become negatively linked to bank stability in Africa. The authors find that macro-prudential action and monetary policy both have a positive and significant relationship with bank stability. The authors provide evidence to support that the marginal effect of excessive credit risk and insolvency risk on bank stability is reduced when interacted with monetary and macro-prudential regulations, and the impact is significant in strong institutional environment.

Research limitations/implications
Future research should extend data to include developing and emerging economies in the world. Also, policymakers, researchers and practitioners should consider different regulatory and institutional frameworks in explaining the relationship between the thresholds of bank risk exposures and bank stability in the world.

Practical implications
Regulatory authorities should have to deeply reform their financial systems, develop risk-based regulatory framework and effective supervision mechanism relating to appropriate techniques that maintain an optimal and desired level of bank risks and risk-taking behaviours required to ensure a stable banking system.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine how different regulatory frameworks shape the non-linear impact of bank risk exposures on bank stability in Africa.

The inclusion of immediate and lagged climate responses amplifies the effect of climate autocorrelation on long‐term growth rate of populations
Authors: Evers Sanne M. , Knight Tiffany M. , Compagnoni Aldo 
Published: June 2023

Abstract

Climate variability will increase with climate change, and thus it is important for population ecologists to understand its consequences for population dynamics. Four components are known to mediate the consequences of climate variability: the magnitude of climate variability, the effect size of climate on vital rates, covariance between vital rates and autocorrelation in climate. Recent studies have pointed to a potential fifth component: vital rates responding to climate in different timeframes, with some responding more immediately and some having lagged responses.

We use simulations to quantify how all five components modify the consequences of climatic variability on long‐term population growth rates across a range of life histories defined by life expectancy and iteroparity. We use an established method to compose Matrix Population Models for 147 life histories.

Our simulations show that including different timeframes for vital rates responses to climate can either reduce or amplify the negative influence of climate variability on long‐term population growth rates. The negative effect of different timeframes for vital rates responses on population growth is amplified when climatic autocorrelations are negative, and when species are long‐lived.

Synthesis. The existing literature shows that vital rates often respond to climate in different timeframes, and that studies often ignore climate autocorrelation. Our results show that simultaneously including both of these factors can substantially increase or decrease a population's expected growth rate. Moreover, the relative magnitude of this change increases with the generation time of a life history. Our results are relevant to conservation, population forecasts and population modelling in general.
Getting to the root: Examining within and between home health agency inequities in functional improvement

Published: June 2023

AbstractObjectiveTo quantify racial, ethnic, and income‐based disparities in home health (HH) patients' functional improvement within and between HH agencies (HHAs).Data Sources2016–2017 Outcome and Assessment Information Set, Medicare Beneficiary Summary File, and Census data.Data Collection/Extraction MethodsNot Applicable.Study DesignWe use multinomial‐logit analyses with and without HHA fixed effects. The outcome is a mutually exclusive five‐category outcome: (1) any functional improvement, (2) no functional improvement, (3) death while a patient, (4) transfer to an inpatient setting, and (5) continuing HH as of December 31, 2017. The adjusted outcome rates are calculated by race, ethnicity, and income level using predictive margins.Principal FindingsOf the 3+ million Medicare beneficiaries with a HH start‐of‐care assessment in 2016, 77% experienced functional improvement at discharge, 8% were discharged without functional improvement, 0.6% died, 2% were transferred to an inpatient setting, and 12% continued using HH. Adjusting for individual‐level characteristics, Black, Hispanic, American Indian/Alaska Native (AIAN), and low‐income HH patients were all more likely to be discharged without functional improvement (1.3 pp [95% CI: 1.1, 1.5], 1.5 pp [95% CI: 0.8, 2.1], 1.2 pp [95% CI: 0.6, 1.8], 0.7 pp [95% CI:0.5, 0.8], respectively) compared to White and higher income patients. After including HHA fixed effects, the differences for Black, Hispanic, and AIAN HH patients were mitigated. However, income‐based disparities persisted within HHAs. Black‐White, Hispanic‐White, and AIAN‐White disparities were largely driven by between‐HHA differences, whereas income‐based disparities were mostly due to within‐HHA differences, and Asian American/Pacific Islander patients did not experience any observable disparities.ConclusionsBoth within‐ and between‐HHA differences contribute to the overall disparities in functional improvement. Mitigating functional improvement inequities will require a diverse set of culturally appropriate and socially conscious interventions. Improving the quality of HHAs that serve more marginalized patients and incentivizing improved equity within HHAs are approaches that are imperative for ameliorating outcomes.
Addressing the atomic bomb damage: Associations between ‘state compensation’ demands and aspects of survivors' suffering
Authors: Vasileva Vladisaya Bilyanova , Izumi Shizue , Kawano Noriyuki 
Published: June 2023

AbstractTo address the long‐lasting consequences of the atomic bombings in Hiroshima and Nagasaki, in 1994, the Japanese government implemented the current in‐force Atomic Bomb Survivors Support Law. This substantial policy offers medical, health and welfare measures and even incorporates some reparations‐like aspects. Nevertheless, atomic bomb survivors' organisations have severely criticised the government for failing to adequately address the entirety and inhumanity of the atomic bomb damage by refusing to enact the law on a clearly stated principle of ‘state compensation’. As such, we attempt to clarify empirically what aspects of survivors' suffering are most closely associated with their demands for ‘state compensation’. Based on statistical model‐based analysis, survivors who deem that ‘state compensation’ should be enacted experience frequent flashbacks of the bombings, disadvantaged life opportunities and economic concerns, among others. We conclude the study by considering the difficulty in addressing the consequences of nuclear weapons use and testing through programmes that approximate, but fail to establish, clear reparations‐based measures, such as the current Atomic Bomb Survivors Support Law.
Reproductive and morphological analysis of the trairão Hoplias intermedius in the São Francisco River, downstream from a large reservoir

Published: June 2023

AbstractHoplias intermedius, of the Characiformes order and Erytrinidae family, is widely distributed across South America. This commercially interesting species can reach a length of 100 cm and a weight of 15–20 kg. To evaluate the reproductive biology of H. intermedius in the São Francisco River, Brazil, 154 males and 190 females were captured bi‐monthly between September 2018 and August 2019 from the downstream regions of the Três Marias dam. Gillnets with differently sized meshes were deployed at distances of 34–54 km after the confluence with the Abaeté River (18°00′49″ S, 45°10′51″ W). Biometric data, gonadosomatic index (GSI), Fulton condition factor (K) and absolute fecundity (AF) were determined for each specimen. Gonad maturation stages and the spawning season were also established. The biometric data, GSI and K average values were relatively higher in females than in males. The reproductive peak for both sexes was reached around January/February. The mean AF was 4300.5 ± 1451.2 follicles per female. Fully developed vitellogenic follicles had a mean diameter of 1014.8 ± 250.7 μm, which is characteristic of fish with moderate fecundity. Fish of all maturation stages, from mature, spawned and spermed, occurred in all bimesters, indicating that this species reproduced throughout the year. The high frequency of spawning females throughout the year and the histological characteristics of spawned ovaries indicated that trairão H. intermedius' spawning type is partial.
