AbstractMovement of animals and plants from mainland populations contributes to the genetic diversity and viability of geographically isolated island biota, but also carries risks of pathogen introductions. The bat fauna of the island of Trinidad reflects species diversity on the neighbouring South American mainland and includes the common vampire bat (Desmodus rotundus). We determined relationships between Trinidad and mainland vampire bat populations and the extent of mainland-island movement by comparing the genetic structure (nuclear and mitochondrial) and morphology of the TrinidadianD. rotunduspopulation to populations in neighbouring regions of the South American mainland and estimating evolutionary histories and patterns of gene flow.Results indicate that TrinidadianD. rotundusare genetically and morphologically distinct from mainland populations, although limited unidirectional male-biased mainland to island gene flow occurs at an estimated rate of 3.3 migrants per year. Two geographically-definedDesmoduscytochromebclades were identified within Trinidad (i.e., one restricted to the South-Western peninsula which grouped with Venezuelan sequences and the other found throughout the rest of the island which grouped with sequences from Suriname and Guyana) suggesting long-standing female philopatry. The geographic distribution of these clades mirrors that of two previously identified geographically defined rabies virus (RABV) lineages introduced to Trinidad from the mainland. This finding suggests that bat dispersals and RABV introductions occur via both the northern and south-western island peninsulas, with subsequent male-driven intra-island viral spread enabled by bat nuclear homogeneity of these populations. These study findings will contribute to the development of contemporary evidence-based vampire bat population control and rabies prevention programs within island populations.

AbstractMemory, woven into the very fabric of consciousness, serves as a time-traveling vessel in the mind, using detailed recollections not just for nostalgic reflection but as an abstract map for charting unknown futures. Here, we employed fMRI to investigate how the hippocampus (HPC) encodes detailed experiences into abstract knowledge (i.e., formation) and uses this knowledge for decision making (i.e., utilization) when human participants learned and then utilized spatial-temporal relations in a relational memory task. We found a functional gradient along the anterior-posterior axis of the HPC, characterized by representational similarity and functional connectivity with the autobiographical network. Here, the posterior HPC was more actively engaged in memory formation, whereas the anterior HPC was predominantly involved in memory utilization. Our computational modeling of relational memory further established a causal link between this functional gradient and the HPC’s well-documented anatomical gradient, as optimal task performance arose from a combination of a fine-grained representation of past experiences by the posterior HPC and a coarser representation of abstract knowledge for future planning by the anterior HPC. This scale-dependent coding scheme led to the emergence of grid-like, heading direction-like, and place-like units in our neural network model, analogous to those discovered in biological brains. Taken together, our study revealed the HPC’s functional gradient in representing relational memory, and further connected it to the anatomical gradient of place cells, supporting a unified framework where both spatial and episodic memory rely on relational representations that integrate spatial localization with temporal continuity.

Published: January 2024

This Letter presents the first lattice QCD computation of the coupled channel πΣ−K¯N scattering amplitudes at energies near 1405 MeV. These amplitudes contain the resonance Λ(1405) with strangeness S=−1 and isospin, spin, and parity quantum numbers I(JP)=0(1/2−). However, whether there is a single resonance or two nearby resonance poles in this region is controversial theoretically and experimentally. Using single-baryon and meson-baryon operators to extract the finite-volume stationary-state energies to obtain the scattering amplitudes at slightly unphysical quark masses corresponding to mπ≈200  MeV and mK≈487  MeV, this study finds the amplitudes exhibit a virtual bound state below the πΣ threshold in addition to the established resonance pole just below the K¯N threshold. Several parametrizations of the two-channel K matrix are employed to fit the lattice QCD results, all of which support the two-pole picture suggested by SU(3) chiral symmetry and unitarity.

Classification of Lifshitz invariant in multiband superconductors: An application to Leggett modes in the linear response regime in Kagome lattice models
Authors: Nagashima Raigo , Tian Sida , Haenel Rafael , Tsuji Naoto , Manske Dirk 
Published: January 2024

Multiband superconductors are sources of rich physics arising from multiple order parameters, which show unique collective dynamics including Leggett mode as relative phase oscillations. Previously, it has been pointed out that the Leggett mode can be optically excited in the linear response regime, as demonstrated in a one-dimensional model for multiband superconductors [T. Kamatani , ]. Here we identify the linear coupling term in the Ginzburg-Landau free energy to be the so-called Lifshitz invariant, which takes the form of d·(Ψi*∇Ψj−Ψj*∇Ψi), where d is a constant vector and Ψi and Ψj(i≠j) represent superconducting order parameters. We classify all pairs of irreducible representations of order parameters in the crystallographic point groups that allow for the existence of the Lifshitz invariant. We emphasize that the Lifshitz invariant can appear even in systems with inversion symmetry. The results are applied to a model of s-wave superconductors on a Kagome lattice with various bond orders, for which in some cases we confirm that the Leggett mode appears as a resonance peak in a linear optical conductivity spectrum based on microscopic calculations. We discuss a possible experimental observation of the Leggett mode by a linear optical response in multiband superconductors.

Effectiveness of digital rhetoric persuasion on GenZ consumer purchasing decisions
Authors: Gupta Hemant , Parmar Bhaveshkumar J. 
Published: January 2024

Purpose
The study aims to analyze the effectiveness of digital rhetoric persuasion on GenZ purchase decision. Digital rhetoric (DR) is an art of persuasion used in social media communication to shape and influence the course of an individual. It has been used in social media advertisements (SMAs) to increase its perceived effectiveness. GenZ consumers are more vibrant than previous generations’ consumers because of high levels of literacy and capacity to adapt to new technology. Therefore, understanding the effects of rhetorical support decisions to act on and mold consumers’ reasoning and judgment is particularly significant in relation to GenZ purchasing decisions and the rhetorical persuasive methods. Concurrently, the moderating effect of generation cohort theory also needs to be examined.

Design/methodology/approach
The threshold model for consumers’ purchase decisions in the form of logistic regression has been applied to examine the impact of DR through SMAs on the purchase intention (PI) of GenZ consumers. Simultaneously, the moderating effect of generation cohort theory is being examined by comparative analysis of different generations’ PI moderation by DR effect.

Findings
The results of the current study reveal that DR via SMAs has a positive and significant influence on GenZ consumers’ PI, whereas other older generation consumers do not get similarly affected by the same.

Originality/value
In an emerging economy like India, where 30% of the population belongs to the GenZ category and the digital advertising industry is growing by double digits, the present study takes a novel approach to examine the impact of DR via SMAs on GenZ consumers’ PI. Concurrently, it also provides an understanding of the moderation effect of generation cohort theory on perceived effectiveness of DR.

Purpose
This study aims to examine the relationship between blockchain technology (BCT) adoption and firm performance (FIP) mediated by cyber-security risk management (CSRM) in the context of Vietnam, a developing country. Besides, the mediating effect of risk-taking tendency (RTT) has been considered in the BCT–CSRM nexus.

Design/methodology/approach
Data is collected using a survey questionnaire of Vietnamese financial firms through strict screening steps to ensure the representativeness of the population. The ending pattern of 449 responses has been used for analysis.

Findings
The findings of partial least squares structural equation modeling demonstrated that CSRM has a positive effect on FIP and acts as a mediator in the BCT–FIP nexus. Furthermore, RTT moderates the relationship between BCT and CSRM significantly.

Practical implications
This study introduces the attractive attributes of applying BCT to CSRM. Accordingly, managers should rely on BCT and take advantage of it to improve investment resources, business activities and functional areas to enhance their firm's CSRM. Especially, managers should pay attention to enhancing their RTT, which improves FIP.

Originality/value
This study supplements the previous literature in the context of CSRM by indicating favorable effects of BCT and RTT. Additionally, this study identifies the effectiveness of RTT as well as its moderating role. Ultimately, this paper has been managed as a pioneering empirical study that integrates BCT, RTT and CSRM in the same model in a developing country, specifically Vietnam.

Published: January 2024

Purpose
The purpose of this study is to identify the most prevalent initiatives undertaken by leading universities in sustainability and offer a roadmap for other institutions seeking to undertake similar actions and contribute to more effective implementation of sustainability practices.

Design/methodology/approach
By using a quantitative assessment approach, the study sheds light on successful initiatives implemented by universities worldwide, spanning six categories: transportation, waste management, curriculum, food and dining, water and energy. Each category is clearly related to one or more of the 17 sustainable development goals. A cluster analysis was also applied to identify regional trends in preferred initiatives.

Findings
The study underlines the importance of integrating sustainability principles into the curricula of higher education institutions (HEIs) as well as educating staff members on energy and water management. The most common and impactful initiatives in the studied six categories have been identified. Many of the initiatives mentioned in the study do not just result in reducing ecological footprint but also provide economic savings as well. Differences among regions and countries were observed in the implementation of initiatives. Cultural and habitual factors should not be disregarded during the selection process of initiatives.

Originality/value
The findings of this study may help universities to take their first steps toward implementing initiatives that can effectively promote sustainable development. Results will aid other HEIs in planning for next steps while outlining the more common initiatives.

Published: January 2024

PurposeThis study aimed to understand better what makes esports fans engage with streamers' live-streaming of esports gameplay. This study used the Theory of Planned Behavior (TPB) and additionally adopted streamer identification and esports game identification as moderating variables.Design/methodology/approachData were collected from streamers' esports content streaming viewers over 18 years of age using an online survey in Amazon M-Turk (N = 307). Based on past esports live-streaming weekly watching hours, which range from 1 to 45 h, the participants were divided into lower (n = 152) and higher (n = 155) frequency groups. PLS-SEM and bootstrapping techniques were used to test the moderated mediation relationships among the constructs.FindingsThis study found a negative moderating effect of past watching experience on the relationship between attitudes and behavioral intention, and it positively moderated the path between perceived behavioral control and behavioral intention. Also, it was found statistically significant direct impacts of streamer identification (STI) and esports game identification (EGI) on attitude and subjective norms. While the indirect impact of STI on behavioral intention through attitude was statistically significant, there were no significant indirect impacts of EGI on attitude and behavioral intention through subjective norms.Originality/valueTheoretically, this study extends the TPB model by exploring the two identifications (i.e. streamers and esports games) as antecedents of the focal TPB factors (i.e. attitudes, subjective norms and perceived behavioral control) and the moderating effect of prior experience based on high/low weekly watching frequencies. Practically, content creators of esports live-streaming and live-streaming platform managers can use the study’s findings to develop strategies to nurture their current and future viewership.
Corrosion beneath the surface? The emotional navigation of managerialist regulation in German welfare organizations
Authors: Betzelt Sigrid , Bode Ingo , Parschick Sarina 
Published: January 2024

PurposeRegarding how the public regulation of human services is perceived within welfare organizations and how the latter cope with it, the role of emotions (as mediators between structure and agency) proves highly relevant while often being hidden beneath the surface. This article shows how a specific approach to such regulation – here: managerialism – may impact on “emotional regimes” at the organizational and individual level, affecting the attainment of organizational goals and workers' health.Design/methodology/approachThe article primarily draws on multiple qualitative case studies across two welfare sectors (four organizations) in Germany (continuing education/active inclusion; long-term care). The study research was conducted between 2020 and 2022 and based on 36 interviews with caseworkers and managers, focus group interviews and expert dialogues at industry level.FindingsThe results suggest that the managerialist regulation of welfare services breeds complex and ambiguous emotional regimes. Business-like management techniques elicit various emotions, affecting the motivational basis of human service work. While the experience of hard challenges may raise positive feelings, coping patterns often put strain on organizations and staff alike. In the short run, related emotional regimes tend to make service delivery proceed smoothly, yet in the long run they may have corrosive effects and problematic repercussions on macro-level developments.Originality/valueThe study highlights the role of emotions in publicly regulated human service settings by intermingling macro- and micro-level processes and thereby broadens the perspective of welfare state research as it reveals the impact of (managerialist) regulation on the dynamic organizational chemistry of such settings.
Generativity of enterprise IT infrastructure for digital innovation

Published: January 2024

PurposeDigital innovation requires organizations to reconfigure their information technology infrastructure (ITI) to cultivate creativity and implement fast experimentation. This research inquiries into ITI generativity, an emerging concept demoting a critical ITI capability for organizational digital innovation. More specifically, it conceptualizes ITI generativity across two dimensions—namely, systems and applications infrastructure (SAI) generativity and data analytics infrastructure (DAI) generativity—and examines their respective social and technical antecedents and their impact on digital innovation.Design/methodology/approachThis research formulates a theoretical model to investigate the social and technical antecedents along with innovation outcomes of ITI generativity. To test this model and its associated hypotheses, a survey was administered to IT professionals possessing knowledge of their organization's IT architecture and digital innovation performance. The dataset, comprising responses from 140 organizations, was analyzed using the partial least squares technique.FindingsResults reveal that both dimensions of ITI generativity contribute to digital innovation performance, with the effect of DAI generativity being more pronounced. In addition, SAI and DAI generativities are driven by social and technical factors within an organization. More specifically, SAI generativity is positively associated with the usage of a digital application services platform and IT human resources, whereas DAI generativity is positively linked to the usage of a data analytics services platform, data analytics services usability and data analytics human resources.Originality/valueThis research contributes to the literature on digital innovation by introducing ITI generativity as a crucial ITI capability and deciphering its role in digital innovation. It also offers useful insights and guidance for practitioners on how to build ITIs to achieve better digital innovation performance.
The role of regulatory focus in consumers' adoption of virtual fitting rooms (VFRs)
Authors: Lee Hanna , Xu Yingjiao , Porterfield Anne 
Published: January 2024

PurposeDespite the potential of virtual fitting rooms (VFRs) to enhance the consumer experience, their adoption is in the preliminary stages. Little is known about inherent reasons why consumers would adopt VFRs. As consumers' attributional processes can be influenced by their enduring chronic traits, this study aims to investigate the influence of chronic regulatory focus on consumers' VFR adoptions via consumers' perceptions of value provided by VFRs. Additionally, the mediating effects of perceived functional and experiential values were examined. Further, the moderating effect of prior VFR experience was tested to allow for variations in consumer experiences.Design/methodology/approachData were collected via an online survey of 480 consumers who have at least heard of VFRs via convenience sampling. Established measures were utilized to develop the survey questionnaire. Data were analysed using structural equation modelling to test the main model with mediation effects as well as multi-group comparisons to test the moderating effect.FindingsEmpirical results revealed that respective chronic regulatory foci, as preconceived factors that drive consumers' differences in processing, exerted significant influences on consumers' perceptions of VFRs, which, in turn, positively influenced their adoption intention. Also, perceived values mediated the relationship between regulatory foci and consumers' adoption intention. Further, prior VFR experience moderated the relationship between regulatory focus and perceived value.Originality/valueThe paper empirically tested the importance of chronic regulatory foci in understanding consumers' cognitive and affective attributional processes, explaining inherent psychological reasons why consumers would (not) adopt VFRs.
Exploring the psychological benefits of green apparel and its influence on attitude, intention and behavior among Generation Z: a serial multiple mediation study applying the stimulus–organism–response model
Authors: Rūtelionė Aušra , Bhutto Muhammad Yaseen 
Published: January 2024

PurposeThis study examines the relationship between green psychological benefits and green apparel purchase behavior using stimulus–organism–response (S-O-R) theory and a serial multiple mediation model.Design/methodology/approachData were collected from 250 Lithuanians using a standardized questionnaire. Convergent and discriminant validity analyses were performed to ensure validity and reliability, and variable relationships were assessed using structural equation modeling.FindingsThe findings revealed utilitarian environmental benefits and warm glow benefits positively impacted Generation Z's (Gen Z's) attitudes toward green apparel. In contrast, the self-expressive benefits had no effect. In addition, attitude and purchase intention significantly predict green apparel purchase behavior. Attitudes and purchase intentions are crucial as serial mediators between green psychological benefits and green apparel purchase behavior.Originality/valueThese findings provide valuable insights for policymakers in Lithuania and highlight the importance of emphasizing the psychological benefits to encourage the purchase of green apparel. Moreover, policymakers and marketers should design apparel products that appeal to Gen Z, promoting green apparel adoption. By leveraging the stimulus–organism–response (S-O-R) theory, this research contributes to understanding pro-environmental behavior. It bridges the gap between attitudes, intentions and actual behavior in sustainable fashion research.
