AbstractThe red-legged partridge,Alectoris rufa(n=38 chromosomes) plays a crucial role in the ecosystem of southwestern Europe, and understanding its genetics is vital for conservation and management. Here we sequence, assemble, and annotate a highly contiguous and nearly complete version of it genome (115 scaffolds, L90=23). This assembly contains 96.9% (8078 out of 8332) orthologous genes from the BUSCO aves_odb10 dataset of single copy orthologous genes. We identify RNA and protein genes, 95% of which with functional annotation. This near-chromosome level assembly revealed significant chromosome rearrangements compared to quail (Coturnix japonica) and chicken (Gallus gallus), suggesting thatA. rufaandC. japonicadiverged 21 M-years ago and that their common ancestor diverged fromG. gallus37 M-years ago. The reported assembly is a significant step towards a complete reference genome forA. rufa, contributing to facilitate comparative avian genomics, and providing a valuable resource for future research and conservation efforts for the red-legged partridge.

Authors: G. Gowtham , R. Jagan Raj 
Published: January 2024

Purpose
The purpose of this study is to find the suitable trajectory path of the Numerical model of the Quadcopter. Quadcopters are widely used in various applications due to their compact size and ease of assembly. Because they are quite unstable, autonomous control systems would be used to overcome this problem. Modelling autonomous control is predominant as the research scope faces challenges because of its highly non-linear, multivariable system with 6 degree of freedom.

Design/methodology/approach
Quadcopters with antonym systems can operate in an unknown environment by overcoming unexpected disturbances. The first objective when designing such a system is to design an accurate mathematical model to describe the dynamics of the system. Newton’s law of motion was used to build the mathematical model of the system.

Findings
Establishment of the mathematical model and the physics behind a four propeller drone for the frame TAROT 650 carbon was done. Simulink model was developed based on the mathematical model for simulating the complete dynamics of the drone as well as location and gusts were included to check the stability.

Originality/value
The control response of the system was simulated numerically results are discussed. The trajectory path was found. The phases with their own parameters can be used to implement the mathematical model for another type of quadcopter model and achieve quick development.

The role of tweets in agricultural export: an approach from text-mining and time-series analyses
Authors: Inoue Yutaro , Nakajima Shinsaku 
Published: January 2024

PurposeThis study aims to investigate the relationship between consumer awareness of Zespri International Limited (Zespri™) and its sales promotion in Japan and the recent expansion of New Zealand (NZ) kiwifruit imported into Japan.Design/methodology/approachTweets mentioning Zespri™ were utilised as a proxy of such awareness. They were first summarised using two text-mining techniques: tf-idf scoring and a co-occurrence network graph. Afterwards, the authors estimated a tri-variate vector autoregression (VAR) model consisting of the net imports of NZ kiwifruit in Japan, unit import price and number of tweets. Additionally, the occurrence frequency of tweets with “Kiwi Brothers”, promotional characters for Zespri™’s sales, was added to the model, and a tetra-variate VAR model was estimated. Finally, Granger-causality tests, an estimation of the impulse response function and forecast error variance decomposition was conducted.FindingsAll these variables were found to Granger-cause each other. Furthermore, a shock in the document frequency of “Kiwi Brothers” significantly affected Japan’s kiwifruit imports from NZ, explaining approximately 20% of future imports. Zespri™’s distinctive sales promotion was, thus, found to contribute in part to the recent increase in NZ’s kiwifruit export to Japan.Originality/valueThis paper is the first to apply text-regression methodology to food consumption research; it contributes to food consumption research by proposing a practical way to combine tweets with outcome variables using a time-series analysis.
Forging a sustainable path: improving India’s (Bharat’s) coal mining operations for a better tomorrow
Authors: Hasanuzzaman  , Chakraborty Kaustov , Bag Surajit 
Published: January 2024

PurposeSustainability is a major challenge for India’s (Bharat’s) coal mining industry. The government has prioritized sustainable growth in the coal mining industry. It is putting forth multifaceted economic, environmental and social efforts to accomplish the Sustainable Development Goals (SDGs). This research aims to identify the factors for sustainable improvements in coal mining operations. Secondly, this study examines the intensity of causal relations among the factors. Thirdly, this study examines whether causal relations exist among the factors to be considered for sustainable improvement in coal mining operations. Lastly, the study aims to understand how the factors ensure sustainable improvement in coal mining operations.Design/methodology/approachAn integrated three-phase methodology was applied to identify the critical factors related to coal mining and explore the contextual relationships among the identified factors. Fifteen critical factors were selected based on the Delphi technique. Subsequently, the fifteen factors were analyzed to determine the contextual and causal relationships using the total interpretive structural modelling (TISM) and DEMATEL methods.FindingsThe study identified “Extraction of Coal and Overburden” as the leading factor for sustainable improvement in coal mining operations, because it directly or indirectly influences the overall mining operation, environmental impact and resource utilization. Hence, strict control measures are necessary in “Extraction of Coal and Overburden” to ensure sustainable coal mining. Conversely, “Health Impact” is the lagging factor as it has very low or no impact on the system. Therefore, it requires fewer control mechanisms. Nevertheless, control measures for the remaining factors must be decided on a priority basis.Practical implicationsThe proposed structural model can serve as a framework for enhancing sustainability in India’s (Bharat’s) coal mining operations. This framework can also be applied to other developing nations with similar sustainability concerns, providing valuable guidance for sustainable operations.Originality/valueThe current study highlights the significance of logical links and dependencies between several parameters essential to coal mining sustainability. Furthermore, it leads to the development of a well-defined control sequence that identifies the causal linkages between numerous components needed to achieve real progress towards sustainability.
The role of social partners in facilitating return to work: a comparative analysis for Belgium and Italy
Authors: Armaroli Ilaria , Akgüç Mehtap 
Published: January 2024

Purpose This study explores how social partners contribute to the successful return to work (RTW) of individuals affected by chronic diseases, employing the framework of actor-centred institutionalism.Design/methodology/approach This paper adopts a comparative case study methodology to assess the role of social partners in the workplace (re-)integration of people with chronic disease in Belgium and Italy, both of which represent well-developed industrial relations systems yet having different institutional and policy frameworks on RTW.Findings Institutional factors are found to affect the type and degree of social partners' commitment and contribution to RTW. Differences in their commitment can be explained by their varied degrees of integration in public policy formation, which explain their different preferred stages of interactions in this field: national tripartite social dialogue for Belgium; and sectoral collective bargaining for Italy. Unsatisfactory outcomes of social partners’ contribution in facilitating RTW processes are attributed to the fragmentation of the legal framework and uneven development of collective bargaining in Italy. In Belgium, the authors find the presence of cumbersome RTW procedures downplaying the role of the worker representative.Originality/value This paper adds empirical evidence to the limited literature on the role of social partners in facilitating RTW and sheds light on how to improve the current policy context. It suggests involving the social partners in the development of a comprehensive public policy framework, which should allow for an early, flexible and multi-stakeholder (re-)integration procedure following chronic disease.

Authors: Yuan Xiaolong , Wang Feng , Deng Mianlin , Shi Wendian 
Published: January 2024

PurposeBased on conservation of resources (COR) theory, this study aims to examine the impact of daily illegitimate tasks on employees' daily silence and daily voice behavior, as well as the mediating role of daily ego depletion and the moderating role of trait mindfulness.Design/methodology/approachThrough daily diary approach, 81 employees were followed for 10 consecutive workdays. Multilevel analysis was employed to examine the hypothesized relationships.FindingsThe results showed that daily illegitimate tasks are positively related to daily silence behavior and negatively related to daily voice behavior; daily ego depletion plays a mediating role in these relationships. Trait mindfulness moderates the effect of daily illegitimate tasks on daily ego depletion and the indirect effect of daily illegitimate tasks on daily silence and daily voice.Practical implicationsManagers should be mindful of minimizing the assignment of illegitimate tasks. Additionally, it is recommended that the organization provide training courses for employees to help them reduce ego depletion. Finally, organizations should focus on fostering high levels of mindfulness among their employees.Originality/valueThis study contributes to the existing literature by investigating the immediate impact of illegitimate tasks on employee voice and silence at within-person level. By doing so, it enhances comprehension of the consequences associated with illegitimate tasks. Meanwhile, this study offers additional insights into the underlying mechanisms and boundary conditions of the effect of illegitimate tasks from a resource perspective.
Entrepreneurship by Ph.D. students: intentions, human capital and university support structures
Authors: Opizzi Matteo , Loi Michela , Macis Orsola 
Published: January 2024

PurposeDoctoral students are promising entrepreneurial actors in university-based ventures, which positively impact the external environment and create value for their universities. In this article, the authors extend current research on academic entrepreneurship by shedding light on the role of university support in the early stage of Ph.D. entrepreneurship. Based on social information processing theory, the authors posit that academic entrepreneurship results from the interplay between doctoral students' human capital and university-level support. A multilevel model is proposed and empirically tested to shed light on the cradle of doctoral students' entrepreneurship by explaining the variance of their entrepreneurial alertness and intentions.Design/methodology/approachA model is proposed that explains the combined effect of specific human capital and different forms of university support on doctoral students' cognitive transition from entrepreneurial alertness to intentions. The model was then tested through structural equation modeling (SEM) and multigroup analysis (MGA) on a sample of 187 doctoral students enrolled in Italian universities.FindingsThe SEM results reveal that doctoral students' entrepreneurial alertness is influenced by perceived educational support and human capital. The MGA demonstrates that those who perceive a higher level of support for concept and business development from universities are more likely to convert their alertness into intentions than those who perceive lower support.Originality/valueThe present paper brings to the stage doctoral students as an extremely promising entrepreneurial target. In doing so, it extends academic entrepreneurship studies by detailing how and when the different forms of university support influence their entrepreneurial decisions, along with individual dimensions.
Co-volatility dynamics in global cryptocurrency and conventional asset classes: a multivariate stochastic factor volatility approach
Authors: Velappan Shalini 
Published: January 2024

Purpose
This study aims to investigate the co-volatility patterns between cryptocurrencies and conventional asset classes across global markets, encompassing 26 global indices ranging from equities, commodities, real estate, currencies and bonds.

Design/methodology/approach
It used a multivariate factor stochastic volatility model to capture the dynamic changes in covariance and volatility correlation, thus offering empirical insights into the co-volatility dynamics. Unlike conventional research on price or return transmission, this study directly models the time-varying covariance and volatility correlation.

Findings
The study uncovers pronounced co-volatility movements between cryptocurrencies and specific indices such as GSCI Energy, GSCI Commodity, Dow Jones 1 month forward and U.S. 10-year TIPS. Notably, these movements surpass those observed with precious metals, industrial metals and global equity indices across various regions. Interestingly, except for Japan, equity indices in the USA, Canada, Australia, France, Germany, India and China exhibit a co-volatility movement. These findings challenge the existing literature on cryptocurrencies and provide intriguing evidence regarding their co-volatility dynamics.

Originality
This study significantly contributes to applying asset pricing models in cryptocurrency markets by explicitly addressing price and volatility dynamics aspects. Using the stochastic volatility model, the research adding methodological contribution effectively captures cryptocurrency volatility's inherent fluctuations and time-varying nature. While previous literature has primarily focused on bitcoin and a few other cryptocurrencies, this study examines the stochastic volatility properties of a wide range of cryptocurrency indices. Furthermore, the study expands its scope by examining global asset markets, allowing for a comprehensive analysis considering the broader context in which cryptocurrencies operate. It bridges the gap between traditional asset pricing models and the unique characteristics of cryptocurrencies.

Authors: Teh Yang Yang 
Published: January 2024

AbstractThis study presents a mixed‐methodology pilot study of a narrative‐mantra multi‐clinician group, which is an integrative systemic and mindfulness‐based intervention, to promote the well‐being of mental health clinicians working at a local child and adolescent mental health service in London, UK. The study also served as a nonclinical sample pilot for a narrative‐mantra multi‐family group trial for adolescents awaiting treatment and their parents. In total, nine clinicians participated in the study: five participants and four controls. Descriptive analyses were conducted on self‐reported measures, GHQ‐12 and SCORE‐15. Slight improvements were found in the clinicians' mental well‐being and their significant relationships. Five global themes emerged from the thematic analysis of a focus group discussion, including ‘voices that connect and liberate’ and ‘connecting ingredients for integration’.
Examining the impact of Medicaid payments for immediate postpartum long‐acting reversible contraception on the mental health of low‐income mothers
Authors: Marthey Daniel , Rochford Hannah , Andreyeva Elena 
Published: January 2024

AbstractObjectiveTo examine the effect of Medicaid immediate postpartum long‐acting reversible contraception (IPP LARC) reforms on self‐reported mental health among low‐income mothers aged 18–44 years.Data Sources and Study SettingWe used national secondary data on self‐reported mental health status in the past 30 days from the core component (2014–2019) of the Behavioral Risk Factor Surveillance System (BRFSS).Study DesignWe estimated linear probability models for reporting any days of not good mental health in the past 30 days. We adjusted for individual‐level factors, state‐level factors, and state and year fixed effects. Our primary independent variable was an indicator for IPP LARC payment reform. We examined the effect of the Medicaid payment reforms on self‐reported mental health status in the past 30 days using difference‐in‐differences and event‐study designs.Data Collection/Extraction MethodsNot applicable.Principal FindingsState adoption of Medicaid IPP LARC reforms was associated with significant reductions (between 5.7% and 11.5%) in the predicted probability of reporting any days of not good mental health among low‐income mothers. Treatment effects appeared to be driven by respondents reporting two or more children (less than 18 years of age) in the household (ATT = ‐0.028, p = 0.04). Results are robust to a series of sensitivity tests and alternative estimation strategies.ConclusionsOur findings suggest that contemporary efforts to improve access to contraceptive methods may have important benefits beyond reproductive autonomy. These findings have implications for policymakers as the landscape related to family planning services continues to shift.

AbstractUnderstanding the genetic basis of adaptive evolution following habitat expansion can have important implications for pest management. The pink rice borer (PRB), Sesamia inferens (Walker), is a destructive pest of rice that was historically restricted to regions south of 34° N latitude in China. However, with changes in global climate and farming practices, the distribution of this moth has progressively expanded, encompassing most regions in North China. Here, 3 highly differentiated subpopulations were discovered using high‐quality single‐nucleotide polymorphism and structural variant datasets across China, corresponding to northern, southern China regions, and the Yunnan‐Guizhou Plateau, with significant patterns of isolation by geographic and environmental distances. Our estimates of evolutionary history indicate asymmetric migration with varying population sizes across the 3 subpopulations. Selective sweep analyses estimated strong selection at insect cuticle glycine‐rich cuticular protein genes which are associated with enhanced desiccation adaptability in the northern group, and at the histone‐lysine‐N‐methyltransferase gene associated with range expansion and local adaptation in the Shandong population. Our findings have significant implications for the development of effective strategies to control this pest.
