Published: August 2023

AbstractBackground and PurposeChronic hemiparetic stroke patients have very limited benefits from current therapies. Brain-computer interface (BCI) engaging the unaffected hemisphere has emerged as a promising novel therapeutic approach for chronic stroke rehabilitation. This study investigated the effectiveness of the IpsiHand System, a contralesionally-controlled BCI therapy in chronic stroke patients with impaired upper extremity motor function. We further explored neurophysiological features of motor recovery affected by BCI. We hypothesized that BCI therapy would induce a broad motor recovery in the upper extremity (proximal and distal), and there would be corresponding changes in baseline theta and gamma oscillations, which have been shown to be associated with motor recovery.MethodsThirty chronic hemiparetic stroke patients performed a therapeutic BCI task for 12 weeks. Motor function assessment data and resting state electroencephalogram (EEG) signals were acquired before initiating BCI therapy and across BCI therapy sessions. The Upper Extremity Fugl-Meyer assessment (UEFM) served as a primary motor outcome assessment tool. Theta-gamma cross-frequency coupling (CFC) was computed and correlated with motor recovery.ResultsChronic stroke patients achieved significant motor improvement with BCI therapy. We found significant improvement in both proximal and distal upper extremity motor function. Importantly, motor function improvement was independent of Botox application. Theta-gamma CFC enhanced bilaterally over the C3 and C4 motor electrodes following BCI therapy. We observed significant positive correlations between motor recovery and theta gamma CFC increase across BCI therapy sessions.ConclusionsBCI therapy resulted in significant motor function improvement across the proximal and distal upper extremities of patients. This therapy was significantly correlated with changes in baseline cortical dynamics, specifically theta-gamma CFC increases in both the right and left motor regions. This may represent rhythm-specific cortical oscillatory mechanism for BCI-driven motor rehabilitation in chronic stroke patients.

AbstractThere are now over 500 medical AI devices that are approved by the U.S. FDA. However, little is known about where and how often these devices are actually used after regulatory approval. In this paper, we systematically quantify the adoption and usage of medical AI in the U.S. by tracking Current Procedural Terminology (CPT) codes explicitly created for medical AI. CPT codes are widely used for documenting billing and payment for medical procedures, providing a measure of device utilization across different clinical settings. We examine a comprehensive nationwide claims database of 16 billion CPT claims between 1/1/2015 to 6/12023 to analyze the prevalence of medical AI based on submitted claims. Our results indicate that medical AI adoption is still nascent, with most usage driven by a handful of leading devices. For example, only AI devices used for assessing coronary artery disease and for diagnosing diabetic retinopathy have accumulated more than 10,000 CPT claims. Furthermore, medical AI usage is moderately over-represented in higher-income zip codes and metropolitan areas. Our study sheds light on the current landscape of medical AI adoption and usage in the U.S., underscoring the need to further investigate barriers and incentives to promote equitable access and broader integration of AI technologies in healthcare.

AbstractDespite great progress in understanding lipoprotein physiology, there is still much to be learned about the genetic drivers of lipoprotein abundance, composition, and function. We used ion mobility spectrometry to survey 16 plasma lipoprotein subfractions in 500 Diversity Outbred (DO) mice maintained on a Western-style diet. We identified 21 quantitative trait loci (QTL) affecting lipoprotein abundance. To refine the QTL and link them to disease risk in humans, we asked if the human homologues of genes located at each QTL were associated with lipid traits in human genome-wide association studies (GWAS). Integration of mouse QTL with human GWAS yielded candidate gene drivers for 18 of the 21 QTL. This approach enabled us to nominate the gene encoding the neutral ceramidase,Asah2, as a novel candidate driver at a QTL on chromosome 19 for large HDL particles (HDL-2b). To experimentally validateAsah2, we surveyed lipoproteins inAsah2-/-mice. Compared to wild-type mice, femaleAsah2-/-mice showed an increase in several lipoproteins, including HDL. Our results provide insights into the genetic regulation of circulating lipoproteins, as well as mechanisms by which lipoprotein subfractions may affect cardiovascular disease risk in humans.

ABSTRACTOur genome is exposed to a wide variety of DNA-damaging agents. If left unrepaired, this damage can be fixed into mutations that promote carcinogenesis and the development of genetically inherited diseases. As a result, it is crucial that we can detect DNA damage and mutations with exquisite sensitivity. Here, we describe a modified version of double barcoding sequencing technology termed Mutation And DNA Damage Detection-seq (MADDD-seq) that can detect DNA damage and mutations simultaneously, with a single assay. To demonstrate the utility of MADDD-seq as a multifunctional detection tool, we treated yeast cells with a DNA-damaging agent and tracked the presence of DNA damage and mutations over a 24-hour timespan. These experiments allowed us to identify thousands of adducts and mutations in a single sequencing run and expose the kinetics of DNA repair and mutagenesis in remarkable detail.
Has increased prominence of translation results changed net investment hedging practice?
Authors: Marshall Beverly , Jin Han 
Published: August 2023

Purpose
The purpose of this paper is to examine the impact of greater reporting prominence of translation results following Accounting Standard Update (ASU) 2011-05 on net investment (NI) hedging practice. The authors investigate the role of increased transparency on the decision to engage in NI hedging (participation), the degree of NI hedging (level) and the hedging vehicle choice.

Design/methodology/approach
This paper uses the Heckman two-stage procedure (Heckman, 1979) in the hedging choice analysis. In the first stage, the authors model the participation decision as a function of reporting transparency, translation results and other control variables. In the second stage, the authors include the Inverse Mills ratio from the first stage Probit to examine both the level and vehicle choice decisions.

Findings
When translation is reported more prominently, the authors find an increase in the level of NI hedging and a greater likelihood of debt as the hedging vehicle, but no evidence firms are more likely to hedge. Regardless of where translation results are reported, firms facing ongoing translation losses are more likely to hedge.

Research limitations/implications
This paper examines S&P 500 firms in the years surrounding the effective date of ASU 2011-05. The findings suggest managers respond to the increase in reporting transparency by increasing hedging for long-term risk management purposes, supporting accounting authorities’ efforts to promote other comprehensive income information transparency. The results should hold for comparable firms with similar currency exposure, size and visibility, but may not apply to smaller firms with limited translation exposure. As only about a quarter of firms with translation exposure engage in NI hedging, the primary results are based on a relatively limited number of firms.

Originality/value
To the best of the authors’ knowledge, this is the first study that examines NI hedging behavior changes following ASU-2011-05. Second, the authors are the first to explore why firms are almost equally split between derivatives and debt as their exclusive hedging vehicle.
A move to the bright side? When journalism is invited into internal communication
Authors: Madsen Vibeke Thøis , Andersen Helle Tougaard 
Published: August 2023

PurposeJournalists moving into corporate communication have for many years been regarded as a move to the “dark side”. This paper turns the lens to explore how trained journalists working as internal communication practitioners due to their journalistic self-concept and skills can contribute to internal communication.Design/methodology/approachAn interview study was conducted with twelve trained journalists working with internal communication in different types of organizations. Three indicators of professionalism, namely autonomy, altruism and expert knowledge, were used as categories to structure the interviews and analysis.FindingsThe respondents perceived that their journalistic self-concept and skills helped them identify the employee perspective, write relevant stories and deliver them quickly. Furthermore, their courage and lack of fear of authorities enabled them to challenge decisions made by their senior managers, especially regarding how, what and when to communicate.Research limitations/implicationsThe three indicators of the journalist profession, – autonomy, altruism and journalistic knowledge and skills – may help establish internal communication that is relevant, transparent and trustworthy.Practical implicationsOrganizations may benefit from building their internal communication around the three indicators of the journalist profession. They could, for example, host independent internal media that present the employees’ perspective and maintain a critical attitude to the organization in a relevant and compelling manner.Originality/valueFew studies have explored the role of journalists working as internal communication practitioners and their contributions to internal communication.
Female CEO and FinTech performance: Are senior directors more inclusive?
Authors: Stefanelli Valeria , Manta Francesco , D'Amato Antonio 
Published: August 2023

Purpose
This paper aims to investigate the relationship between gender diversity in CEO positions and FinTech profitability by exploring the moderating role of the average board age on such a relationship.

Design/methodology/approach
A unique data set of Italian FinTech companies during the 2017–2019 period was used in an ordinary least square model specification. The model is designed to assess the relationship between the presence of a female CEO and FinTech profitability and the moderating role of the average age of governing board members.

Findings
The results of this study indicate that when the average age of the FinTech firm’s board members is relatively low, the profitability of those firms with female CEOs was not significantly different from the profitability of firms with male CEOs. However, among FinTech firms with relatively older board members, the profitability of those firms with a female CEO was lower. This empirical result seems to suggest that older board directors are less prone to recognize female CEO leadership qualities. This supports the need for FinTech firms to adopt good practices in board composition that favor gender inclusion and diversity on board.

Originality/value
The novelty of this study within the literature is that the empirical analysis added new evidence on the relationship between Female CEO and performance by exploring the moderating role of the average age of board members. Moreover, the empirical results of this study suggest specific conditions that could improve the profitability of female-led firms by removing the apparent biased perceptions about the quality of women in leadership among older board members.
Corporate governance in SMEs: a systematic literature review and future research
Authors: Teixeira Jaime Fernandes , Carvalho Amélia Oliveira 
Published: August 2023

Purpose
The purpose of this study is to examine the corporate governance of small and medium enterprises (SMEs) through a systematic literature review.

Design/methodology/approach
The review was conducted by analyzing 19 published studies in the field, leading to the identification of 14 journals and 40 authors. The relationship between corporate governance mechanisms and various aspects of SMEs’ performance was analyzed. The characteristics of corporate governance were classified into five categories: board, ownership, CEO, audit and age.

Findings
The review found a direct relationship between corporate governance mechanisms and various aspects of SMEs’ performance, including innovation, internationalization, auditing and risk of failure. The study also highlights the need for future research to adopt a behavioral perspective, to shift focus from identifying responsibilities to examining governance processes and to use nonlinear models and qualitative methods to effectively analyze the interrelated nature of the phenomena under study.

Research limitations/implications
The limitations of the review include the limited number of studies available for analysis, as well as the fact that most of the empirical research was based on evidence from European countries, with only a few papers focusing on other countries, such as the USA, China and Ghana.

Originality/value
The results of this review provide valuable insights for researchers and practitioners in the field of corporate governance in SMEs. The findings provide a foundational basis for further research in the area and highlight the need for future studies to adopt a behavioral perspective and use nonlinear models and qualitative methods.
The digital transformation in the psychology of workplace spirituality
Authors: Walter Yoshija 
Published: August 2023

PurposeThere is evidence that spirituality at the workplace has positive effects on work outcomes, and there are different models conceptualizing the construct. To date, there is no discussion highlighting how digitalization is affecting workplace spirituality and vice versa. The present review tries to close this gap by discussing the psychological dynamics in light of digitalization and spirituality in the context of work.Design/methodology/approachThis is a conceptual discussion based on an extensive narrative review. The conceptual design is further tested with a real-life case study.FindingsThe result is a model that may guide future research, which consists of the four highly interdependent domains, namely psychology (with the dimensions of emotion, cognition and behavior), digitalization (with the dimensions of platforms, data and algorithms), spirituality (with the dimensions of meaning, self-transcendation and belonging), as well as the workplace (with the dimensions of work tasks, location, community and culture and values). The discussion includes implications for the future of work, suggestions for management decisions and potential future research directions.Originality/valueTo date, there are many discussions about digital transformation and a limited amount of them have invested in analyzing psychological dimensions. The application to spirituality and the workplace – especially when the two are combined – is almost wholly absent, which makes the present discussion both innovative and original.

Who believes political fake news? The role of conspiracy mentality, patriotism, perceived threat to freedom, media literacy and concern for disinformation
Authors: Daunt Kate L. , Greer Dominique A. , Jin Hyun Seung , Orpen Isabella 
Published: August 2023

PurposeUnderstanding individual susceptibility to political fake news is critical because fake news can target specific psychological profiles of vulnerable individuals. Consequently, this research examines five individual risk (i.e. susceptibility) and resilience (i.e. protective) factors, conspiracy mentality, patriotism, perceived threat to freedom, media literacy and concern for disinformation, to determine if they inform belief in political fake news and subsequently, to what degree belief impacts private engagement with political fake news.Design/methodology/approachUsing a fictional political fake news stimulus, the authors conducted a deductive thematic analysis of 10 semi-structured interviews and an online survey of 722 United Kingdom (UK) citizens analysed using structural equation modelling.FindingsConspiracy mentality and patriotism were positively associated with belief in political fake news, while media literacy and concern for disinformation were negatively associated with belief in political fake news. Perceived threat to freedom was a strong theme in the qualitative data but had no statistical effect on belief in political fake news. Belief in political fake news was positively associated with further engagement with the fake news story, acting as a mediator in the model.Originality/valueDistinct from previous research that focuses on partisanship and sharing behaviour, this research forwards a model underpinned by social identity theory to build an integrated understanding of political fake news belief. The results demonstrate that political identity motivations beyond partisanship are salient when examining individual susceptibility to political fake news and that belief in political fake news plays a core role in understanding subsequent private engagement with the story.
Does capital flight tone down economic growth? Evidence from emerging Asia
Authors: Basher Shahanara , Mamun Abdullahil , Bal Harun , Hoque Nazamul , Uddin Mahi 
Published: August 2023

PurposeThis study aims to offer an up-to-date estimate of capital flight from selected emerging Asian economies and examine the anti-growth phenomenon of capital flight by using annual data for the period 1981–2019.Design/methodology/approachThe study relies on residual methods to derive the estimate of capital flight with necessary adjustments. It then applies the autoregressive distributed lag Bounds testing approach in examining the impact of capital flight on the economic growth of Asian emerging economies.FindingsThe study identifies capital flight as the attributor to the slower economic growth of the selected emerging economies of Asia.Practical implicationsApart from appropriate policies addressing the issues causing capital flight, unleashing the way of private sector-led growth of the emerging countries with necessary policy, infrastructural, institutional and regulatory support can rather help them retain and repatriate domestic capital.Originality/valueThe capital flight estimates in earlier studies are antithetical as they differ in terms of definition and estimation procedure. Again, the growth effect of capital flight in these economies has received meager attention in research and policy debates. Furthermore, being country-specific or region-specific, existing studies are unable to compare the growth effect of capital flight for different emerging economies in this region. Examining the growth effects for a large number of countries separately based on a common estimate of capital flight can resolve these issues that this study aims to do.

Authors: Vieira Talita Cristiele Gomes , Ciriaco Luana Alves , Santos Silvana Silva , Souza Gabriel Lucas de , Souza Polibio José de Campos 
Published: August 2023

Purpose
This article aims to analyze the incorporation of harm reduction health workers with lived experience in all services focused on the care for drug users in Belo Horizonte’s mental health network, one of the largest Brazilian Psychosocial Care Networks (Rede de Atenção Psicossocial [RAPS]), and reports the findings of a qualitative study on the life stories, recovery journeys and the professional practice of harm reducers in Belo Horizonte.

Design/methodology/approach
For the development of this research, the authors chose the following methodological tools: documentary research; follow-up of harm reduction interventions; access to harm reducers’ field diaries; joint writing of the life stories of the harm reducers.

Findings
It indicates that these professionals, as harm reducers empowered by their life experience, have developed various elements and active ingredients of peer support. Their practices and the results of their actions have consolidated their inclusion as Belo Horizonte RAPS’ health workers and highlight that recovery-oriented care and peer support are a real possibility in Brazil.

Originality/value
In this research, harm reducers are coauthors and report their own life experience. In this article, they also talk about the impact of this experience on their work and on the lives of users of mental health services, emphasizing the protagonism and exercise of citizenship by harm reducers.
