Published: January 2024

AbstractStep selection analysis is used to jointly describe animal movement patterns and habitat preferences. Recent work has extended this framework to model inter-individual differences, account for unexplained structure in animals’ space use, and capture temporally-varying patterns of movement and habitat selection.In this paper, we formulate step selection functions with penalised smooths (similar to generalised additive models) to unify new and existing extensions, and conveniently implement the models in the popular, open-sourcemgcvR package. We explore non-linear patterns of movement and habitat selection, and use the equivalence between penalised smoothing splines and random effects to implement individual-level and spatial random effects. This framework can also be used to fit varying-coefficient models to account for temporally or spatially-heterogeneous patterns of selection (e.g., resulting from behavioural variation), or any other non-linear interactions between drivers of the animal’s movement decisions. We provide the necessary technical details to understand several key special cases of smooths and their implementation inmgcv, showcase the ecological relevance using two illustrative examples, and provide R code (available athttps://github.com/NJKlappstein/smoothSSF) to facilitate the adoption of these methods. This paper is a broad overview of how smooth effects can be applied to increase the flexibility and biological realism of step selection analysis.
SRCompiler: Translating Stella dynamic models to open-source R scripts

Published: January 2024

AbstractStella Architect (iSee Systems) offers an object-oriented environment that facilitates the development of dynamic models. Stella, however, does not support some of the advanced mathematical tools that can be found in mathematical software such as R. Moreover, R is open source, contains numerous libraries and resources, and is used by a large community. However, building dynamic systems, which typically use a large number of differential or difference equations, are more difficult to build in R. To take advantage of both Stella and R, we have developed the SRCompiler (Stella-R Compiler), which is a translator that exports models built in Stella into R scripts. In 2012, a translator from Stella to R was developed based on plain text treatment for Stella, but it had some limitations such as scalability and error handling. Nevertheless, our approach is more versatile, scalable and expandable since it is based on compiler design, defines a formal language, and uses the latest Stella version (v. Architect).In this paper, a classical predator-prey model has been modelled in Stella to show an applied example. Following the translation of the Stella model into R, all the parameters of the model (6 in total) have been optimised to fit model output to the Hudson Bay Company’s hare-lynx time series hunting data (1847-1935).Software availabilityName of software: SRCompilerSRCompiler Developers: Pastor Héctor.M, Morales EnriqueWeb page:https://github.com/hmpp91/SRCompilerAvailable: 2021Program language: C++Program size: 197 KBAvailability and cost: Open source
New groups of highly divergent proteins in families as old as cellular life with important biological functions in the ocean

Published: January 2024

AbstractBackgroundMetagenomics has considerably broadened our knowledge of microbial diversity, unravelling fascinating adaptations and characterising multiple novel major taxonomic groups, e.g. CPR bacteria, DPANN and Asgard archaea, and novel viruses. Such findings profoundly reshaped the structure of the known tree of life and emphasised the central role of investigating uncultured organisms. However, despite significant progresses, a large portion of proteins predicted from metagenomes remain today unannotated, both taxonomically and functionally, across many biomes and in particular in oceanic waters, including at relatively lenient clustering thresholds.ResultsHere, we used an iterative, network-based approach for remote homology detection, to probe a dataset of 40 million ORFs predicted in marine environments. We assessed the environmental diversity of 53 gene families as old as cellular life, broadly distributed across the Tree of Life. About half of them harboured clusters of environmental homologues that diverged significantly from the known diversity of published complete genomes, with representatives distributed across all the oceans. In particular, we report the detection of environmental clades with new structural variants of essential genes (SMC), divergent polymerase subunits forming deep-branching clades in the polymerase tree, and variant DNA recombinases of unknown origin in the ultra-small size fraction.ConclusionsThese results indicate that significant environmental diversity may yet be unravelled even in strongly conserved gene families. Protein sequence similarity network approaches, in particular, appear well-suited to highlight potential sources of biological novelty and make better sense of microbial dark matter across taxonomical scales.
Consumption of only wild foods induces large-scale, partially-persistent alterations to the gut microbiome

Published: January 2024

AbstractThe composition of the gut microbiome (GM) affects human health and varies among lifestyles. Adopting more “traditional” diets could lead to substantive and health-associated changes in the GM. However, research has focused on diets including domesticated foods. For most of our evolutionary history, humans consumed only wild foods. We explored the impact of a wild-food-only (WF) diet on the GM composition. One participant collected daily fecal samples and recorded daily food consumption over an eight-week period, the middle four weeks of which he consumed only wild foods (nuts, fruits and leafy greens, wild deer, and fish). Samples were profiled through 16S rRNA amplicon sequencing and the species identified by oligotyping. The WF diet altered the GM composition, and the magnitude of the changes is larger than in other diet interventions. However, no new GM taxa, including “old friends” appeared; instead, the relative proportions of already-present taxa shifted. There is a clear successional shift from the pre-, during- and post-WF diet. The GM is very sensitive to the change from a “Western” diet to a WF diet, likely reflecting the different macro- and micronutrient properties of the consumed foods.

AbstractHuman papillomaviruses (HPV) are a major cause of malignancy, contributing to ∼5% of all human cancers worldwide, including most cervical cancer cases and a growing number of ano-genital and oral cancers. The major HPV viral oncogenes, E6 and E7, manipulate many host cellular pathways that promote cell proliferation and survival, predisposing infected cells to malignant transformation. Despite the availability of highly effective vaccines, there are still no specific anti-viral therapies targeting HPV or treatments for HPV-associated cancers. As such, a better understanding of viral-host interactions may allow the identification of novel therapeutic targets. Here, we demonstrate that the actin-binding protein LASP1 is upregulated in cervical cancer and significantly correlates with a poorer overall survival. In HPV positive cervical cancer, LASP1 depletion significantly inhibited proliferationin vitro, whilst having minimal effects in HPV negative cervical cancer cells. Furthermore, we show that the LASP1 SH3 domain is essential for LASP1-mediated proliferation in these cells. Mechanistically, we show that HPV E7 regulates LASP1 at the post-transcriptional level by repressing the expression of miR-203, which negatively regulatedLASP1mRNA levels by binding to its 3’UTR. Finally, we demonstrated that LASP1 expression is required for the growth of HPV positive cervical cancer cells in anin vivotumourigenicity model. Together, these data demonstrate that HPV induces LASP1 expression to promote proliferation and survival role in cervical cancer, thus identifying a potential therapeutic target in these cancers.
Gravity current escape from a topographic depression
Authors: Skevington Edward W. G. , Hogg Andrew J. 
Published: January 2024

An inertial gravity current released within a topographic depression may climb up the incline from a lower to an upper plateau if it is sufficiently energetic and then continue to flow unsteadily away from the step while simultaneously draining back into the depression. This density-driven motion is investigated theoretically using the shallow-water equations to simulate the flow up a smooth step from a lower to an upper horizontal plane and to compute the volume of fluid that escapes from the depression. It is shown that it is possible for all of the fluid to drain back down the step and that the volume of the escaped fluid diminishes with a power-law dependence on time. This phenomenon is explained by analyzing the unsteady flow of a gravity current along a semi-infinite horizontal plane along which the front advances but simultaneously fluid drains from the rear edge of the plane. The dynamics of this motion at early times is calculated both numerically and analytically. The latter exploits the hodograph transformation of the shallow water equation, a technique which allows rapid and precise evaluation of flow features such as reflections and the onset of bores. The flow at later times becomes self-similar, and the self-similarity is of the second kind. It features an anomalous exponent that provides the power-law dependence of the volume of fluid on time, and this exponent is a function of the imposed Froude number at the front of the current. In this way the diminishing volume of fluid that escapes from a topographic depression is explained quantitatively. Eventually the flow may transition to a regime in which drag becomes non-negligible; the model of simultaneous propagation and draining is extended to this regime to show that the escaped volume of fluid also decays temporally and ultimately vanishes.

Wurtzite TmAlN (Tm=transition metal) themselves are of interest as semiconductors with tunable band gap, insulating motifs to superconductors, and piezoelectric crystals. Characterization of wurtzite TmAlN is challenging because of the difficulty to synthesize them as single-phase solid solution and such thermodynamic, elastic properties, and high temperature behavior of wurtzite Ti1−xAlxN is unknown. Here, we investigated the high temperature decomposition behavior of wurtzite Ti1−xAlxN films using experimental methods combined with first-principles calculations. We have developed a method to grow single-phase metastable wurtzite Ti1−xAlxN (x=0.65, 0.75, 085, and 0.95) solid-solution films by cathodic arc deposition using low duty-cycle pulsed substrate-bias voltage. We report the full elasticity tensor for wurtzite Ti1−xAlxN as a function of Al content and predict a phase diagram including a miscibility gap and spinodals for both cubic and wurtzite Ti1−xAlxN. Complementary high-resolution scanning transmission electron microscopy and chemical mapping demonstrate decomposition of the films after high temperature annealing (950∘C), which resulted in nanoscale chemical compositional modulations containing Ti-rich and Al-rich regions with coherent or semicoherent interfaces. This spinodal decomposition of the wurtzite film causes age hardening of 1–2 GPa.

Work–life balance: Does leadership matter?
Authors: Sani Kareem Folohunso , Adisa Toyin Ajibade 
Published: January 2024

PurposeThe extant literature on work–life balance (WLB) has generally overlooked the interrelationship between leadership and WLB. Does leadership have any impact on employees' use of WLB policies and practices? To answer this question, this article considers the social exchange theory as well as transformational and transactional leadership in an investigation of the impact of leadership on WLB.Design/methodology/approachThe study employs qualitative data from 32 semi-structured interviews to achieve the study’s objectives.FindingsThe research reveals that leadership does matter in WLB. The study findings reveal that both the transactional and transformational leadership styles result in the establishment of strong reciprocal relationships between leaders and employees in terms of using WLB policies and practices. Managers only sanction the use of WLB policies and practices only as a reward for excellent performance or when they are completely sure the outcome will favour the organisation. The study concludes that the desire to achieve WLB has often led many employees to go the extra mile in carrying out their work duties, which is rewarded with an approval to use WLB policies and practices. These non-contractual exchanges emphasise reciprocity and are based on trust.Research limitations/implicationsThe extent to which the findings of this research can be generalised is constrained by the size and nature of the research sample.Practical implicationsMany managers are transactional leaders, and they purposefully allow their employees to use WLB policies and practices only as a reward for meeting targets and for excellent performance. This means that employees who fall short of the required targets and expected performance are not permitted to use WLB policies and practices. This finding implies that such employees experience incessant work–family conflict, which may have negative implications for their work engagement, overall well-being and work performance.Originality/valueThis study demonstrates that leadership is relevant to WLB. It shows that transformational leadership is supportive of WLB, as it considers employees' work performance and non-work outcomes. The results and practical implications of this study aids the understanding of the non-contractual exchanges involved in manager–employee relationships, which is crucial for ensuring employees' achievement of WLB and for organisations to achieve their goals.

Call it a customer club! How reward programme’s name impacts programme effectiveness
Authors: Mimouni Chaabane Aïda , Pez Virginie , Butori Raphaëlle 
Published: January 2024

PurposeThe purpose of this research is to identify how a reward programme name (“loyalty programme” (LP) versus “customer club” (CC)) influences the type of central rewards expected and their impact on loyalty to the retailer.Design/methodology/approachThe authors conducted a survey followed by an experiment.FindingsCentral rewards from programmes called LP are equally hard and soft, whereas central rewards from programmes called CC are mainly soft. Providing customers with central rewards increases satisfaction with the programme and loyalty to the retailer, but only for programmes called LP.Practical implicationsLoyalty managers are advised to pay particular attention to the consistency between the type of rewards they offer and the reward programme name that carries them. Contrary to the name LP that leads to me-too programmes, the name CC offers more flexibility to choose the rewards, providing opportunities to stand out from competing programmes.Originality/valueBy building on a new and original theoretical approach, this research is the first attempt to investigate the effect of the reward programme naming decisions on customers' evaluations and responses.
Influencer advertising: facilitating poor-fitting influencer posts
Authors: Hawkins Matthew A. , Saleem Fathima Z. 
Published: January 2024

PurposeRecent literature identifies the importance of influencer-brand fit, a congruence between the narrative of the social media influencer (SMI) and the branded product being reviewed, on purchase intentions. In creating brand-related content, SMIs can post content that can be either sponsored by the brand or unsponsored. This research merges these literature streams to examine how influencer-brand fit impacts purchase decisions and whether sponsorship status moderates this relationship.Design/methodology/approachUsing a 2 (poor vs good influencer-brand fit) × 2 (sponsored vs unsponsored post) experimental design (n = 198), the relationship between influencer-brand fit and purchase intention, the mediating role of SMI trust and the moderating role of perceived sponsorship are tested. The PROCESS macro was used to analyze direct and indirect paths.FindingsThe results demonstrate that influencer trust mediates the relationship between influencer-brand fit and purchase intention, highlighting the importance of a congruent influencer and brand image in both increasing influencer trust and purchase intentions. Surprisingly, despite the reductions in purchase intentions from conducting a poor-fitting review, purchase intentions are the same between a poor-fitting unsponsored review and a good fitting sponsored review.Practical implicationsDecision-makers of both corporations and SMI personal brands should consider influencer-brand fit when selecting SMI partners to sponsor and brands to work with, respectively, and should aim for good fit between both parties. SMIs should avoid conducting sponsored, poor-fitting product reviews to limit reductions in trust. Influencers seeking to branch out of their area of expertise can initially consider unsponsored content before venturing into sponsored partnerships. Companies seeking to widen their reach through poor-fitting SMIs should consider alternative strategies to sponsorship.Originality/valueAs sponsored content is common, it is necessary to merge the influencer-brand fit and influencer sponsorship literature. Additionally, this study considers the mediating role of influencer trust, an important variable in predicating purchase intentions as well as helping SMI grow their audience.
