The influence of negative travel-related experience on tourist’s brand loyalty
Authors: de Cosmo Lucrezia Maria , Piper Luigi , Mileti Antonio , Guido Gianluigi 
Published: May 2023

AbstractPerceptions of negative events related to service disruptions, negative consumer associations with other brand users, or business activities not in line with consumer ethical standards can lead consumers to abandon and change a brand. Focusing on a low-cost airline company, the study analyses how negative events can affect brand loyalty by considering the mediating effect of consumers’ psychological characteristics in terms of difficulty in choosing between alternatives (choice difficulty) and tendency to switch brands (brand switcher). The paper tests two hypotheses by administering a structured questionnaire to a sample of 260 tourists and shows that: (1) brand switcher negatively mediates the relationship between negative events and brand loyalty; (2) choice difficulty positively mediates the relationship between negative events and brand loyalty. The findings carry theoretical and managerial implications and confirms the value of communication strategies in increasing brand loyalty.
Nonlinear approximation in bounded orthonormal product bases
Authors: Kämmerer Lutz , Potts Daniel , Taubert Fabian 
Published: May 2023

AbstractWe present a dimension-incremental algorithm for the nonlinear approximation of high-dimensional functions in an arbitrary bounded orthonormal product basis. Our goal is to detect a suitable truncation of the basis expansion of the function, where the corresponding basis support is assumed to be unknown. Our method is based on point evaluations of the considered function and adaptively builds an index set of a suitable basis support such that the approximately largest basis coefficients are still included. For this purpose, the algorithm only needs a suitable search space that contains the desired index set. Throughout the work, there are various minor modifications of the algorithm discussed as well, which may yield additional benefits in several situations. For the first time, we provide a proof of a detection guarantee for such an index set in the function approximation case under certain assumptions on the sub-methods used within our algorithm, which can be used as a foundation for similar statements in various other situations as well. Some numerical examples in different settings underline the effectiveness and accuracy of our method.
Artificial intelligence’s right to life
Authors: Milczarek Ewa 
Published: May 2023

AbstractThe right to life is fundamental and primary and is a precondition for exercising other rights (Ramcharan in Ramcharan (ed), The right to life in International Law, Martinus Nijhoff Publishers, Dordrecht, 1985). Its universal recognition in the arena of international law is associated with the concept of a human being endowed with inherent and inalienable dignity. Categorization of the circle of entities covered with the right to life today seems obvious and indisputable. Intense development of artificial intelligence, also the fact that it has passed the Turing test which checks AI’s thinking ability in a way similar to human reasoning, inspires a reflection on AI’s future legal status. This study will investigate a thesis of whether artificial intelligence may be entitled to the right to life. The analysis will be carried out around an exploratory question: what are the requirements for being afforded protection of the right to life?
Two Types of Ritual Space at the Poverty Point Site 16WC5
Authors: Clay R. Berle 
Published: May 2023

AbstractTwo types of features at the Late Archaic period Poverty Point site in Louisiana—large timber post circles and repetitively used activity surfaces later covered by mounding—are examined as spaces that were the products of historical event sequences involving their construction, their entwined but differing ritual uses, and their final deconstruction or removal. This approach is a particularizing, historicizing way of approaching the features of this monumental hunter-gatherer site, an alternative to a more generalizing view in which its totality as a site or “place” is seen as the interrelated product of many historical acts over time or as a mosaic of historically created and used “spaces.” Analysis of these feature types suggests that spaces of ritual activity in the larger site were used differently, involving different types of events and serving different functions in a developing, perhaps shifting, larger ritual landscape.
Establishing the normative and comparative needs of assistive technology provision in Queensland from the agency and funding scheme perspective
Authors: Hogan Christy , Gustafsson Louise , Di Tommaso Amelia , Hodson Tenelle , Bissett Michelle , Shirota Camila 
Published: May 2023

AbstractBackground and Aims:Assistive technology services and devices support the participation and inclusion of people living with disability. In Australia, the regulatory bodies, agencies and schemes that manage assistive technology provision are governed by national and / or state-based Acts and Legislation. This study examined the assistive technology sector from the perspective of the regulatory bodies, agencies and schemes.Design and Methods:Regulatory bodies, agencies and schemes that manage funding for assistive technology in Australia were identified by the research team. A website audit reviewed publicly available documents and information. Semi-structured interviews with representatives from the agencies and schemes were audio-recorded and transcribed verbatim.Findings:The audit (n =17) found that the range and level of information publicly available was variable. The availability of assistive technology for driving and transport, design and building for access and safety, and mobility was most often promoted. The qualitative findings (n = 11) indicated variability and challenges within four themes: operationalising the legislation; internal assistive technology processes; reasonable and necessary; and risks in the assistive technology pathway.Conclusions:Regulatory bodies, agencies and schemes are critical to the effectiveness of the sector. The findings identified opportunities for the organisations to review how internal processes are communicated publicly, and for the sector to address the perceived risks related to health professional availability, knowledge and skills, and limited accessibility to trial assistive technology. Subsequent studies explored the perspectives of the assistive technology advisors and suppliers and the recipients of assistive technology services and devices.
Emerging grammars in contemporary Yoruba phonology
Authors: Adebayo Taofeeq 
Published: May 2023

AbstractThis article provides a description and an Optimality Theory (OT) analysis of contact-induced changes and variation in contemporary Yoruba syllable structure. The article claims that a major diachronic change has occurred in the syllable structure of Yoruba phonology due to its continued contact with English, resulting in the invention, preservation, and hypercorrection of clusters and codas. I characterize this change in terms of OT constraint re-ranking (Miglio and Moren 2003) and assess the resulting synchronic variation against the indexed constraint approach of Itô and Mester (1995a, b, 1999), the ranked-winners approach of Coetzee (2004), the partial-order co-phonology of Anttila (1997), and the Maximum Entropy (MaxEnt) model of Goldwater and Johnson (2003). I show that none of these approaches is able to account independently for the categorical, gradient, and lexically conditioned variation that characterize the contemporary Yoruba syllable structure, but rather that a MaxEnt model augmented with lexical indexation is the most economical model that fits the Yoruba data accurately.
Co-creation and engagement in a DNA integrity cohort study
Authors: Parker L. Lynette , Bonner Chantel M. , Sobol Robert W. , Arrieta Martha I. 
Published: May 2023

Abstract

Introduction:
The partnership between a research community engagement team (CE Team) and a community advisory board (CAB) formed the basis for bidirectional communication in developing resources for participant recruitment in a DNA integrity study. Engaging with a minoritized community, this partnership focused on respect, accessibility, and expanded engagement.

Methods:
A ten-member CAB, working in two groups defined by meeting time convenience, provided insight and feedback to the CE Team in the creation of recruitment and consent materials, via an iterative design process in which one CAB group reviewed and enhanced materials, and the second group tested and refined them further. The continuous analysis of CE Team notes from CAB meetings captured information needed both for materials refinement and implementation of CAB-suggested activities.

Results:
The partnership resulted in the co-creation of recruitment and consent materials that facilitated the enrollment of 191 individuals into the study. The CAB encouraged and assisted in expanded engagement inclusive of community leaders. This broader engagement provided information about the DNA integrity study to community decision-makers as well as responded to questions and concerns about the research. The bidirectional communication between the CAB and the CE Team encouraged the researchers to consider topics and research interests related to the current study but also responsive to community concerns.

Conclusions:
The CAB helped the CE Team develop a better understanding of the language of partnership and respect. In this way, the partnership opened doors for expanded community engagement and effective communication with potential study participants.

Abstract
Ecological and genetic factors have influenced the composition of the human microbiome during our evolutionary history. We analysed the oral microbiota of the Agta, a hunter–gatherer population where some members have adopted an agricultural diet. We show that age is the strongest factor modulating the microbiome, probably through immunosenescence since we identified an increase in the number of species classified as pathogens with age. We also characterised biological and cultural processes generating sexual dimorphism in the oral microbiome. A small subset of oral bacteria is influenced by the host genome, linking host collagen genes to bacterial biofilm formation. Our data also suggest that shifting from a fish/meat diet to a rice-rich diet transforms their microbiome, mirroring the Neolithic transition. All of these factors have implications in the epidemiology of oral diseases. Thus, the human oral microbiome is multifactorial and shaped by various ecological and social factors that modify the oral environment.
Fragmented Control of Platform Game Work in China
Authors: Zhao Mengyang 
Published: May 2023

AbstractThis article adopts a labour process theory approach to analysing distinct circuits of labour control in platform video game work in China, a novel manifestation of the platform economy rooted in the special formation of Chinese gaming infrastructure as well as in precarious labour regimes. Platform game work encompasses a broad range of online video game services such as live game streaming, paid boosting, and game companion, matching customers’ demands to workers who provide entertainment or assist play. Platform game work has drawn an estimated seven million young workers into precarious employment during the past decade. The article outlines three interwoven features defining the fragmented control of platform game work: the crucial function of extra-platform intermediaries in regulating labour processes; the deployment of relationship labour in order matching and community management; and the mutual reinforcement of platform diversity and fast-moving platform architecture. These three features co-create a decentralised yet resilient structure organised by a network of platform and non-platform, human and machine agencies. Positioning platform game work in the broad spectrum of gig work, the article illuminates new modes of labour control and workers’ embedded agency, adding to the nascent literature on diverse labour regimes and subjectivities in the platform economy.
Rate, risk factors and estimations of time to develop severe acute malnutrition after children receiving antiretroviral therapy at selected health facilities in northwest Ethiopia

Published: May 2023

Abstract
Severe acute malnutrition (SAM) affects up to 50 % of children with HIV, especially those who reside in resource-constrained healthcare setting like Ethiopia. During subsequent follow-up of children factors related to incidence of SAM after antiretroviral therapy (ART) is set on, however, there is no prior evidence. An institution-based retrospective cohort study was employed among 721 HIV-positive children from 1 January to 30 December 2021. Data were entered using Epi-Data version 3.1 and exported to STATA version 14 for analysis. Bi-variable and multivariable Cox-proportional hazard models were employed at 95 % confidence intervals to identify significant predictors for SAM. According to this result, the overall mean (±sd) age of the participants was found to be 9⋅83 (±3⋅3) years. At the end of the follow-up period, 103 (14⋅29 %) children developed SAM with a median time of 30⋅3 (13⋅4) months after ART initiation. The overall incidence density of SAM was found to be 5⋅64 per 100 child (95 % CI 4⋅68, 6⋅94). Children with CD4 counts below the threshold [AHR 2⋅6 (95 % CI 1⋅2, 2⋅9, P = 0⋅01)], disclosed HIV status [AHR 1⋅9 (95 % CI 1⋅4, 3⋅39, P = 0⋅03)] and Hgb level ≤10 mg/dl [AHR 1⋅8 (95 % CI 1⋅2, 2⋅9, P = 0⋅03)] were significant predictors for SAM. Significant predictors of acute malnutrition were having a CD4 count below the threshold, children who had previously reported their HIV status, and having haemoglobin <10 mg/dl. To ensure better health outcomes, healthcare practitioners should improve earlier nutritional screening and consistent counselling at each session of care.
A branching random walk in the presence of a hard wall
Authors: Roy Rishideep 
Published: May 2023

AbstractWe consider a branching random walk on a d-ary tree of height n (
$n \in \mathbb{N}$
), in the presence of a hard wall which restricts each value to be positive, where d is a natural number satisfying
$d\geqslant2$
. We consider the behaviour of Gaussian processes with long-range interactions, for example the discrete Gaussian free field, under the condition that it is positive on a large subset of vertices. We observe a relation with the expected maximum of the processes. We find the probability of the event that the branching random walk is positive at every vertex in the nth generation, and show that the conditional expectation of the Gaussian variable at a typical vertex, under positivity, is less than the expected maximum by order of
$\log n$
.
A first-passage-place problem for integrated diffusion processes
Authors: Lefebvre Mario 
Published: May 2023

AbstractLet
${\mathrm{d}} X(t) = -Y(t) \, {\mathrm{d}} t$
, where Y(t) is a one-dimensional diffusion process, and let
$\tau(x,y)$
be the first time the process (X(t), Y(t)), starting from (x, y), leaves a subset of the first quadrant. The problem of computing the probability
$p(x,y)\,:\!=\, \mathbb{P}[X(\tau(x,y))=0]$
is considered. The Laplace transform of the function p(x, y) is obtained in important particular cases, and it is shown that the transform can at least be inverted numerically. Explicit expressions for the Laplace transform of
$\mathbb{E}[\tau(x,y)]$
and of the moment-generating function of
$\tau(x,y)$
can also be derived.
The Far-Right’s Mnemonic Alliance with Putin’s Russia: L’SNS’s Mastering of a Disruptive Past
Authors: Paulovičová Nina , Gyárfášová Oľga 
Published: May 2023

AbstractThis study identifies the mnemonic strategies of the Slovak extreme-right Ľudová Strana Naše Slovensko (ĽSNS) / People’s Party Our Slovakia as a means of establishing a mnemonic alliance with Putin’s Russia. ĽSNS’s construction of mnemonic culture surrounding two critical events in Slovak history – the 1944 Slovak National Uprising and the 1968 invasion of Czechoslovakia by the Soviet army and its allies – is marked by an effort to overcome the ideological divide between its extreme-right ideology and Russia’s identity and memory politics rooted in its anti-fascist heritage. Those two events represent an uneasy terrain for building political and mnemonic alliances between ĽSNS and Putin’s Russia. Even though these two historical milestones represent a seemingly unmasterable past and an obstacle in an ĽSNS-Russia alliance, the party implemented several mnemonic strategies to reconfigure the place of these two key historical events in national memory and clear the path for a closer alliance with Putin’s Russia. We argue that ĽSNS’s memory construction is multidirectional rather than competitive or discordant. We unpack ĽSNS’s memory construction and identify multidirectional effects and trajectories as vectors for building a mnemonic alliance with Putin’s Russia.

AbstractBackgroundIndividuals with bipolar disorder are commonly correctly diagnosed a decade after symptom onset. Machine learning techniques may aid in early recognition and reduce the disease burden. As both individuals at risk and those with a manifest disease display structural brain markers, structural magnetic resonance imaging may provide relevant classification features.MethodsFollowing a pre-registered protocol, we trained linear support vector machine (SVM) to classify individuals according to their estimated risk for bipolar disorder using regional cortical thickness of help-seeking individuals from seven study sites (N = 276). We estimated the risk using three state-of-the-art assessment instruments (BPSS-P, BARS, EPIbipolar).ResultsFor BPSS-P, SVM achieved a fair performance of Cohen's κ of 0.235 (95% CI 0.11–0.361) and a balanced accuracy of 63.1% (95% CI 55.9–70.3) in the 10-fold cross-validation. In the leave-one-site-out cross-validation, the model performed with a Cohen's κ of 0.128 (95% CI −0.069 to 0.325) and a balanced accuracy of 56.2% (95% CI 44.6–67.8). BARS and EPIbipolar could not be predicted. In post hoc analyses, regional surface area, subcortical volumes as well as hyperparameter optimization did not improve the performance.ConclusionsIndividuals at risk for bipolar disorder, as assessed by BPSS-P, display brain structural alterations that can be detected using machine learning. The achieved performance is comparable to previous studies which attempted to classify patients with manifest disease and healthy controls. Unlike previous studies of bipolar risk, our multicenter design permitted a leave-one-site-out cross-validation. Whole-brain cortical thickness seems to be superior to other structural brain features.
Sex steroid receptors in the ovarian follicles of the lizard Sceloporus torquatus

Published: May 2023

SummaryEstradiol and progesterone have been recognized as important mediators of reproductive events in the female mainly via binding to their receptors. This study aimed to characterize the immunolocalization of the estrogen receptor alfa (ERα), estrogen receptor beta (ERβ) and progesterone receptor (PR) in the ovarian follicles of the lizard Sceloporus torquatus. The localization of steroid receptors has a spatio-temporal pattern that depends on the stage of follicular development. The immunostaining intensity of the three receptors was high in the pyriform cells and the cortex of the oocyte of previtellogenic follicles. During the vitellogenic phase, the granulosa and theca immunostaining was intense even with the modification of the follicular layer. In the preovulatory follicles, the receptors were found in yolk and additionally, ERα was also located in the theca. These observations suggest a role for sex steroids in regulating follicular development in lizards, like other vertebrates.

SummaryAlthough ethanol treatment is widely used to activate oocytes, the underlying mechanisms are largely unclear. Roles of intracellular calcium stores and extracellular calcium in ethanol-induced activation (EIA) of oocytes remain to be verified, and whether calcium-sensing receptor (CaSR) is involved in EIA is unknown. This study showed that calcium-free ageing (CFA) in vitro significantly decreased intracellular stored calcium (sCa) and CaSR expression, and impaired EIA, spindle/chromosome morphology and developmental potential of mouse oocytes. Although EIA in oocytes with full sCa after ageing with calcium does not require calcium influx, calcium influx is essential for EIA of oocytes with reduced sCa after CFA. Furthermore, the extremely low EIA rate in oocytes with CFA-downregulated CaSR expression and the fact that inhibiting CaSR significantly decreased the EIA of oocytes with a full complement of CaSR suggest that CaSR played a significant role in the EIA of ageing oocytes. In conclusion, CFA impaired EIA and the developmental potential of mouse oocytes by decreasing sCa and downregulating CaSR expression. Because mouse oocytes routinely treated for activation (18 h post hCG) are equipped with a full sCa complement and CaSR, the present results suggest that, while calcium influx is not essential, CaSR is required for the EIA of oocytes.
