ABSTRACTThe genomes of the fungusMagnaporthe oryzaethat causes blast diseases on diverse grass species, including major crop plants, have indispensable core-chromosomes and may contain one or more additional supernumerary chromosomes, also known as mini-chromosomes. The mini-chromosome is speculated to play a role in fungal biology, provide effector gene mobility, and may transfer between strains. To understand and study the biological function of mini-chromosomes, it is crucial to be able to identify whether a given strain ofM. oryzaepossesses a mini-chromosome. In this study, we applied recurrent neural network models, more specifically, Bidirectional Long Short-Term Models (Bi-LSTM), for classifying DNA sequences as core-or mini-chromosomes. The models were trained with sequences from multiple available core- and mini-chromosome assemblies. The trained model was then used to predict the presence of the mini-chromosome in a global collection ofM. oryzaeisolates using short-read DNA sequences. The model predicted that the mini-chromosome was prevalent inM. oryzaeisolates, including those isolated from rice, wheat, Lolium and many other grass species. Interestingly, 23 recent wheat strains collected since 2005 all carried the mini-chromosome, but none of nine early strains collected before 1991 had the mini-chromosome, indicating the preferential selection for strains carrying the mini-chromosome in recent years. Based on the limited sample size, we found the presence of the mini-chromosome in isolates of pathotypeEleusinewas not as high as isolates of other pathotypes. The deep learning model was also used to identify assembled sequence contigs that were derived from the mini-chromosome and partial regions on core-chromosomes potentially translocated from a mini-chromosome. In summary, our study has developed a reliable method for categorizing DNA sequences and showcases an application of recurrent neural networks in the field of predictive genomics.

AbstractStress Echocardiography (ECG) is a commonly used modality for detection and assessment of Ischemic heart diseases (IHD). Its non-invasive nature makes it a more reliable diagnostic tool. This modality induces myocardial stress through exercise or pharmacological agents. Stress Echocardiography induced by exercise stress tests are more physiologic than pharmacologic stress tests as its finding tells about a patient’s exercise capacity which is prognostically important. Thus, if a patient can exercise, this is the preferred stress modality. Moreover, its radiation-free nature makes it a preferred option for individuals with contraindications to other stress imaging techniques and also decreases complications associated with other cardiac imaging modalities. Clinical conditions can be accurately assessed by comparing the findings of the heart rate and electrocardiograms after stress echocardiography with normal state. Analysis of stress echocardiography is done by visual precise evaluation of impaired myocardial contractility and regional wall motion abnormalities. This modality shows excellent results with current technology and by using an image enhancing agent, where necessary. It can identify the location of myocardial ischemia as well. Stress echocardiography holds significant potential in changing outcomes for a large population of patients with its high diagnostic accuracy, risk stratification capabilities, and cost-effectiveness.

AbstractTransposable elements (TEs) have long been shown to have deleterious effects on the survival and reproduction of their host organism. As TEs are mobile DNA that jump to new positions, this deleterious cost can occur directly, by inserting into genes and regulatory sequences. Classical population genetic theory suggests copy-number dependent selection against TEs is necessary to prevent TEs from expanding so much they take over a genome. Such models have been difficult to interpret when applied to large genomes like maize, where there are hundreds of thousands of TE insertions that collectively make up 85% of the genome. Here, we use nearly 5000 inbred lines from maize mapping populations and a pan-genomic imputation approach to measure TE content. Segregating TE content gives rise to 100 Mb differences between individuals, and populations often show transgressive segregation in TE content. We use replicated phenotypes measured in hybrids across numerous years and environments to empirically measure the fitness costs of TEs. For an annual plant like maize, grain yield is not only a key agronomic phenotype, but also a direct measure of reproductive output. We find weak negative effects of TE accumulation on grain yield, nearing the limit of the efficacy of natural selection in maize. This results in a loss of one kernel (≈0.1% of average per-plant yield) for every additional 14 Mb of TE content. This deleterious load is enriched in TEs within 1 kilobase of genes and young TE insertions. Together, we provide rare empirical measurements of the fitness costs of TEs, and suggest that the TEs we see today in the genome have been filtered by selection against their deleterious consequences on maize fitness.
Determinants of apartment price volatility in Vietnam: a comparison between Hanoi and Ho Chi Minh City
Authors: Nguyen Nhung Thi , Nguyen Lan Hoang Mai , Do Quyen , Luu Linh Khanh 
Published: September 2023

Purpose
This paper aims to explore factors influencing apartment price volatility in the two biggest cities in Vietnam, Hanoi and Ho Chi Minh City.

Design/methodology/approach
The study uses the supply and demand approach and provides a literature review of previous studies to develop four main hypotheses using four determinants of apartment price volatility in Vietnam: gross domestic product (GDP), inflation rate, lending interest rate and construction cost. Subsequently, the Vector Error Correction Model (VECM) is used to analyze a monthly data sample of 117.

Findings
The research highlights the important role of construction costs in apartment price volatility in the two largest cities. Moreover, there are significant differences in how all four determinants affect apartment price volatility in the two cities. In addition, there is a long-run relationship between the determinants and apartment price volatility in both Hanoi and Ho Chi Minh City.

Research limitations/implications
Limitations related to data transparency of the real estate industry in Vietnam lead to three main limitations of this paper, including: this paper only collects a sample of 117 valid monthly observations; apartment price volatility is calculated by changes in the apartment price index instead of apartment price standard deviation; and this paper is limited by only four determinants, those being GDP, inflation rate, lending interest rate and construction cost.

Practical implications
The study provides evidence of differences in how the above determinants affect apartment price volatility in Hanoi and Ho Chi Minh City, which helps investors and policymakers to make informed decisions relating to the real estate market in the two biggest cities in Vietnam.

Social implications
This paper makes several recommendations to policymakers and investors in Vietnam to ensure a stable real estate market, contributing to the stability of the national economy.

Originality/value
This paper provides a new approach using VECM to analyze both long-run and short-run relationships between macroeconomic and sectoral independent variables and apartment price volatility in the two biggest cities in Vietnam.
Entrepreneurial intentions’ temporal stability – intraindividual and group-level analyses
Authors: Figueiredo Belchior Ricardo , Lyons Roisin 
Published: September 2023

Purpose
Entrepreneurial intention (EI) has been studied prolifically, as a precursor to entrepreneurial action, and a desired outcome of entrepreneurship education. Yet, the paucity of extant studies that analyze its temporal stability has been noted. This paper aims to address this gap by studying the temporal stability of EI, investigating its persistence as an attitudinal state over time.

Design/methodology/approach
A series of intraindividual and group-level longitudinal analyses were undertaken, over an 11-year period, using a student sample from Portugal. The authors highlight the magnitude of EI change over time, where item-structure, relative and absolute stability and group and individual-level EI changes are all considered.

Findings
Results indicate an initially strong to moderate EI item-structure stability and relative stability over the first five years, with moderate signs of deterioration. This deterioration becomes even more pronounced across the full 11-year period. Regarding EI absolute stability, while college students (as a group) did not display a general tendency to develop higher or lower EI during the first five years, a small deterioration was found over the 11-year period. At the individual level, EI instability was detected, and this increased with time. Finally, the exploratory results suggest that entrepreneurship education may buffer the deterioration of EI.

Practical implications
The findings provide a more nuanced reasoning for dampened EI–entrepreneurial behavior associations and highlight key determinants of EI change, which can inform educational experts and policymakers.

Originality/value
The legitimacy of the EI field lays heavily on the existence of a stable EI construct and a strong relationship between intentions and behavior. The methodology provides a new and more complete picture of EI’s temporal stability.

Driving financial results is not the only priority! An exploration of the future role of chief financial officer: a grounded theory approach
Authors: Chatpibal Manoj , Chaiyasoonthorn Wornchanok , Chaveesuk Singha 
Published: September 2023

Purpose
This study aims to develop a conceptual framework for the role of chief financial officer (CFO) in an ever-changing environment. As previous research focused on responding to specific crises, there have been theoretical and practical gaps in the role of CFO. The study's goal is to fill a critical gap by developing a comprehensive and integrated set of roles to assist the CFO in a constantly changing environment.

Design/methodology/approach
Using a grounded theory approach, semi-structured interviews and observations were conducted with 21 CFOs from various industries in Thailand, including foreign multinational corporations and domestic companies with international operations. CFOs were asked how they frame their roles in the face of an ever-changing environment and how they prepare for the future.

Findings
The iCFO model is developed, which identifies the critical “core” roles of the CFO in securing the business foundation, as well as the “future opportunities” roles that function as growth engines for long-term business strength. The research delves into the importance of integrity, ethical mindset and corporate governance in the role of the CFO. The iCFO model is designed to help guide future research and provide practical applications for CFOs in both domestic and international contexts. The term “core” refers to the CFO’s primary responsibilities, which include driving profitability, managing risks and optimizing business performance. The “future opportunities” component focuses on the roles that CFOs can play in strengthening the future of business by optimizing investment efficiency, driving digital transformation and being the CEO’s business partner. The findings also emphasized “integrity,” which must encompass all decisions, actions or recommendations made by the CFO.

Originality/value
The study offers unique perspectives on an emerging economy, providing new insights. Through interviews with 21 CFOs, it contributes empirical evidence on the development of roles in accounting and finance, emphasizing good governance practices. The findings highlight the integrated role of the CFO and their self-reflection on their value within the company. Significantly, the study's implications are relevant and applicable to a global audience, particularly in developing economies that prioritize growth. Future studies could incorporate integrated thinking into the iCFO model to address social, environmental and economic factors, making it more universally relevant. Additionally, exploring the adoption of the chief value officer context in developing markets could enable CFOs to expand their focus beyond financial metrics, embracing a comprehensive approach to value creation. By integrating these concepts into the iCFO model, CFOs can effectively drive sustainable and impactful business outcomes on a global scale.
Long-term orientation and corporate social responsibility in small and medium-sized enterprises: the role of strategy formation mode
Authors: Rosecká Nikola , Machek Ondřej , Stasa Michele , Kubíček Aleš 
Published: September 2023

Purpose
This study aims to explore the effects of long-term orientation (LTO) and strategy formation mode on corporate social responsibility. While many researchers have investigated how large businesses address corporate social responsibility (CSR), there is little empirical evidence on how small- and medium-sized businesses implement CSR or what individual drivers shape this process.

Design/methodology/approach
The paper surveyed 282 small and medium-sized managers from the United Kingdom. The respondents were recruited using platform Prolific Academic.

Findings
The findings reveal that LTO is a prerequisite for developing CSR and shapes strategy formation mode. The findings also suggested that deliberate strategies are positively related to CSR. The results are consistent across different components of LTO (futurity, continuity and perseverance) and CSR types (internal and external).

Originality/value
The results show that all aspects of LTO are relevant for CSR in SMEs. Besides LTO, deliberate strategy formation model is an important factor contributing to CSR. The paper presents as first an empirical contribution to the strategy literature by examining positive relationship between LTO and deliberate strategy formation mode.
Detection of varicella‐zoster virus in two dermatomes of herpes zoster duplex bilateralis in an immunocompetent host
Authors: Ono Hiroto , Yamaguchi Reimon , Anzawa Kazushi , Shimizu Akira 
Published: September 2023

AbstractAn 85‐year‐old woman with no history of herpes zoster (HZ) presented with a primary lesion of erythema and blistering on her left thigh and a secondary similar lesion on her right chest which had appeared at 4 and 3 days before presentation, respectively. Tzanck smears for both lesions were positive, revealing multinucleated giant cells. Immunochromatography to detect varicella‐zoster virus (VZV) antigen (DermaQuick®VZV) showed positive on the left thigh at initial onset but negative on the right chest at subsequent onset. The latter repeatedly tested negative for VZV by DermaQuick®VZV. A skin biopsy of the subsequent onset area revealed giant cells, and inclusion bodies were observed in the epidermis. Immunohistochemical staining with anti‐VZV antibody and polymerase chain reaction to detect VZV DNA were positive. The patient was diagnosed with HZ duplex bilateralis and treated with acyclovir. The right thoracic region of the posterior part of the lesion became negative for DermaQuick®VZV. It is thought that expression of viral antigens was suppressed in the right thoracic region, i.e., the late‐onset area.
A re‐evaluation of the effects of mechanical cockle dredging in the Dutch Wadden Sea
Authors: van der Meer Jaap , Folmer Eelke 
Published: September 2023

Abstract

Marine bivalves provide an important seafood resource, but conflicts between bivalve fisheries and conservation goals may arise.

A scientific debate about cockle dredging in the Dutch Wadden Sea resulted in an apparent consensus among scientists of a severe and long‐lasting impact of the mechanical fisheries, and the fisheries were banned.

Specifically, two highly cited papers concluded that the fisheries caused a strong reduction in bivalve recruitment for a period of 8 years and that the fisheries led to the loss of red knots from the Dutch Wadden Sea and a decline of the European wintering population.

Here, we show that these papers had severe shortcomings in terms of data selection and data analysis and we challenge their conclusions.
How Does Foreign Acquirers’ ESG Misbehaviour Exposure Affect the Completion of Cross‐Border Acquisitions?
Authors: Zhu Shan , Du Jian , Lu Jie , Zheng Qiuxia 
Published: September 2023

AbstractThis study investigates how foreign acquirers’ environmental, social and governance (ESG) misbehaviour exposure affects the completion of cross‐border acquisitions (CBAs), and how this impact varies according to citizen power in the target country and the presence of deal rumours. Using a sample of CBAs attempted by Chinese listed firms from 2011 to 2019, we find that foreign acquirers with higher ESG misbehaviour exposure are more likely to fail in CBA completions. As citizen power in the target country increases, such acquirers face greater challenges in CBA completion. In addition, deal rumours can make matters worse (akin to pouring fuel on a fire), putting foreign acquirers with high ESG misbehaviour exposure in a more unfavourable position. Overall, our findings shed light on the concerns and resistance of stakeholders in the target country towards a foreign acquirer with ESG misbehaviour exposure and demonstrate boundary conditions for such an adverse effect.
CITY OF NON‐EQUIVALENTS: Making, Maintaining and Disrupting Customary Attachments to Land in Port Vila, Vanuatu
Authors: Day Jennifer 
Published: September 2023

AbstractIn this article I describe how a permanent underclass is being inadvertently created in a South Pacific city. I use Descola's idea of equivalence in human relations to explain urban tenure and evictions in the postcolonial South Pacific city of Port Vila. Vanuatu is a nation of 82 islands. Its archipelagic geography segregates most people's autochthonous lands, preventing ready access to the national capital. Port Vila, then, is a city of non‐citizens of the urban space: by accident of birth, a small number of people now control the land where virtually all poor migrants to the capital will live. This article describes how two non‐equivalent relations—production and protection—feature prominently in the ways that people talk about tenure insecurity. In sum, these non‐equivalent relations form the basis of how people relate to each other in terms of urban land occupancy. The pervasiveness of non‐equivalence indicates a fundamental difference between denizens of Pacific cities, whose urban policies will need to adapt to account for its presence. A right to the city may look different in places where non‐equivalence is at the very stamba (foundation) of how the city is made.
Toxicity of plants as insecticides against human pathogenic mosquito vectors of Saudi Arabian strains—A review
Authors: Aziz Al Thabiani , Panneerselvam Chellasamy , Edward‐Sam Edwin 
Published: September 2023

AbstractMosquitoes (Diptera: Culicidae) are considered to be huge threat among millions of peoples, animals, and other living organisms in the world. Most of the vector borne diseases such as malaria, filariasis, dengue hemorrhagic fever, chikungunya, Japanese encephalitis etc., created huge impact on humans in all over the world. Vector diseases in Kingdom of Saudi Arabia are increasing day by day and their control measures taken through the government sectors for eradicating the vectors helps in controlling the diseases but still more approaches to be implemented or assimilated. Most of the synthetic or chemical based insecticides to control mosquitoes developed resistance among their communities even though they showed their potential in controlling the vector in initial days. Botanical insecticides from plant‐based origin such as active compounds, essential oils, green synthesized nanomaterials, and microbial secondary metabolites helps more efficiency in controlling vectors. Mode of action against vectors differs based on its persisting active ingredients, such as larvicidal, pupicidal, adulticidal, oviposition, morphological changes etc. Even though number of research works has been carried out against mosquito species, there is only limited number of studies undergone against mosquito vectors from Saudi Arabia origin. Hence this review will give us the current knowledge on the effectiveness of botanical insecticides against major mosquito vectors from Saudi Arabia. Thus, it gives more significant against medical and veterinary sectors.
