We revisit the time evolution of initially trapped Bose-Einstein condensates in the Gross-Pitaevskii regime. We show that the system continues to exhibit BEC once the trap has been released and that the dynamics of the condensate is described by the time-dependent Gross-Pitaevskii equation. Like the recent work [15], we obtain optimal bounds on the number of excitations orthogonal to the condensate state. In contrast to [15], however, whose main strategy consists of controlling the number of excitations with regard to a suitable fluctuation dynamics $t\mapsto e^{-B_t} e^{-iH_Nt}$ with renormalized generator, our proof is based on controlling renormalized excitation number operators directly with regards to the Schrödinger dynamics $t\mapsto e^{-iH_Nt}$.
Human genetic structure of Iberian populations has been thoroughly explored in the last decades. The internal diversity of the Iberian Peninsula becomes visible by the different phylogeographic origins of particular mitochondrial DNA and Y chromosome lineages, which show a high degree of population specificity. In the present study, we combined information on matrilineal and patrilineal variation patterns in two autochthonous populations from Andalusia region (southern Spain). A special focus is made to a male sample set where both uniparental data are available. Gene diversities estimates yielded not statistically significant differences between both types of samples and markers. Genetic ancestry among Andalusians seems to be constituted by three foremost continental origins: European, African, and Middle Eastern. The examined male group has revealed a noticeable proportion of individuals (over 45%) with a non-correspondence between maternal and paternal haplogroup origins, a signal of different population demographic histories linked to both sexes in the past. Andalusian males seem to be well differentiated according to ancestries. As expected, mtDNA diversity was much higher than that for the Y chromosome, a fact that can be caused by patrilocality, which leads to particular social structures with effects on haploid genomes in modern human populations.
Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is an invasive tropical pest that is currently expanding in its geographical range into temperate regions. This study examined the temporal and spatial dynamics of B. dorsalis along an altitudinal gradient in Mpumalanga Province, South Africa, in its southernmost adventive limit, which experiences a temperate climate with dry winters. Populations were monitored from October 2020 to October 2022 at three sites with altitudes ranging from 452 to 1 741 m above sea level. At each site, clusters of attractant-based traps (methyl eugenol and three-component Biolure) were set up and serviced at least monthly. We analysed the effects of climate, time of the year, altitude, and landscape on B. dorsalis abundance. Single population peaks of B. dorsalis were recorded from mid-summer to autumn in all sites, with higher prevalence at the low-altitude site. In the low- and mid-altitude sites, catches were recorded year-round, while at the high-altitude site, there were no catches for four to six months after onset of winter. Higher B. dorsalis catches were recorded as temperatures increased and precipitation decreased. Catches were higher in commercial orchards and home gardens compared to abandoned orchards. These findings provide valuable information for improving simulation models of B. dorsalis distribution and population growth that can be used to inform the management of this pest.
As with the peopling of the Pacific Islands, the monumental ritual architecture of East Polynesia is presumed to have spread from West Polynesia. By re-examining the wealth of absolute dates available from ritual contexts across these diverse islands, the authors challenge this generalisation in Polynesian ideological materialisation, identifying three phases of development. They argue that initial west-to-east migration spread the concept of ritual spaces marked by stone uprights c. AD 1000–1300, then the formalisation of monuments diffused in the opposite direction c. AD 1300–1600, before megastructures emerged from localised hierarchisation, perhaps earliest on Rapa Nui c. AD 1350–1500.
Genetic evidence indicates that Progamotaenia macropodis Beveridge, 1976 (Cestoda: Anoplocephalidae), found in various macropodid host species, is a complex of cryptic species. However, the genetic data are incomplete, and no morphological re-appraisal of the species has been undertaken since its original description. Here, additional mitochondrial cytochrome c oxidase I sequence data have been added from the type host, Macropus giganteus, as well as other host species, and a morphological study of all available material undertaken. A new species, Progamotaenia mollicula sp. nov., is erected for specimens from the tammar wallaby, Notamacropus eugenii, which are smaller, and the testes in pre-mature and mature proglottids occur invariably in two lateral groups. Specimens from the remaining host species, Macropus fuliginosus, Notamacropus parryi, N. rufogriseus, Osphranter robustus, and Wallabia bicolor are highly variable with obvious differences in length and proglottid shape, but with no reliable internal morphological characters for separating the various genotypes. The study was limited by incomplete molecular data (N. rufogriseus) and the poor quality of some of the preserved material.
The quality of news reports about suicide can influence suicide rates. Although many researchers have aimed to assess the general safety of news reporting in terms of adherence to responsible media guidelines, none have focused on major US cable networks, a key source of public information in North America and beyond.
Aims
To characterise and compare suicide-related reporting by major US cable television news networks across the ideological spectrum.
Method
We searched a news archive (Factiva) for suicide-related transcripts from ‘the big three’ US cable television news networks (CNN, Fox News and MSNBC) over an 11-year inclusion interval (2012–2022). We included and coded segments with a major focus on suicide (death, attempt and/or thoughts) for general content, putatively harmful and protective characteristics and overarching narratives. We used chi-square tests to compare these variables across networks.
Results
We identified 612 unique suicide-related segments (CNN, 398; Fox News, 119; MSNBC, 95). Across all networks, these segments tended to focus on suicide death (72–89%) and presented stories about specific individuals (61–87%). Multiple putatively harmful characteristics were evident in segments across networks, including mention of a suicide method (42–52%) – with hanging (15–30%) and firearm use (12–20%) the most commonly mentioned – and stigmatising language (39–43%). Only 15 segments (2%) presented a story of survival.
Conclusions
Coverage of suicide stories by major US cable news networks was often inconsistent with responsible reporting guidelines. Further engagement with networks and journalists is thus warranted.
The water buffalo farm with intensive breeding techniques promotes the spread of lice (Haematopinus tuberculatus), leading to a reduction in meat and milk productions. Current control measures include the use of chemicals, which in the long-term lead to the development of resistance. Given the lack of alternative solutions, the aim of this study was to evaluate the repellent effect of a low impact by-product, the wood vinegar (WV), against H. tuberculatus using a new in vitro bioassay test. The test consisted of a glass Petri dishes subdivided in 3 separate areas. WV was tested at different concentrations (100%, 75%, 50%, 25%). Each of the 3 replicates was performed with 10 adults, at 27 °C and 75% relative humidity. Observations were made 5, 15, 30, 60, 90, 120 and 180 min after application to evaluate movement, the living/dead ratio and the ability to overcome the obstacle area of the lice, in terms of comparative avoidance (%). Additional in vitro cytotoxicity tests were performed. The test performed showed a repellent effect of 77% for the 100% WV concentration against lice of both sexes 30 min after exposure, similar (P < 0.05) to the repellent effect of deltamethrin (77%). The in vitro bioassay developed during the experiment proved to be reliable and can be used to evaluate the repellent effect of new molecules against lice before testing them in vivo. Furthermore, WV has a potential to be a valid tool for the control of buffalo pediculosis, although in vivo studies have to be undertaken.
Elevated non-high-density lipoprotein cholesterol (non-HDL-C) is a significant risk factor for atherosclerotic cardiovascular diseases, particularly in individuals with metabolic syndrome (MetS) and major psychiatric disorders (MPDs), who may experience metabolic side effects of psychopharmacological treatments. We evaluated the cholesterol-lowering effects of an experimental pasta characterized by a high content of phytosterols, arabinoxylans, polyunsaturated and monounsaturated fatty acids, and vitamin E in individuals with MetS, with and without MPDs.
Methods
In a double-blind, randomized trial, 298 participants with MetS were assigned to consume either experimental or conventional pasta for 3 months. Non-HDL-C levels were measured at baseline and follow-up. A polygenic risk score for hypercholesterolemia (TC-PRS) was calculated to assess any genetic influence on the intervention’s efficacy. The cholesterol-lowering effect of the experimental pasta was also tested in vitro by exposing human hepatocarcinoma cells, which developed lipid storage alterations due to olanzapine (OLZ) exposure, to an extract of the flour mixture used to prepare the experimental pasta.
Results
The participants who consumed the experimental pasta exhibited a significantly greater reduction in serum non-HDL-C levels compared to the control group (p = 0.001). No significant interaction between pasta variety and the TC-PRS on non-HDL-C changes was found. The extract from the experimental flour mixture significantly reduced both the number and size of lipid droplets in HepG2 cells treated with OLZ.
Conclusions
These results indicate that a low-impact lifestyle intervention may offer a practical strategy for improving the cholesterol profile and mitigating cardiovascular risk in patients with MetS, with and without an MPD.
Cet article porte sur le limitarisme économique. Nous y explorons la possibilité d’établir une relation entre deux éléments abordés séparément dans cette littérature, soit les incitatifs économiques négatifs que l’application de la théorie peut générer et sa capacité à défendre l’égalité politique. Sur la base de cette relation, nous formulons une nouvelle objection contre le limitarisme. Finalement, nous envisageons deux pistes de solution pour répondre à cette objection et nous en tirons quelques recommandations pour de futures recherches sur le sujet.
To explain why nurses intend to stay or leave their organizations after perceiving a psychological contract breach (PCB), we investigated whether perceived organizational support (POS) among nurses moderates the relationship between PCB and turnover intention (TI). We used a survey methodology targeting currently employed nurses. After controlling for nursing unit, POS accentuated the positive relationship between PCB and TI. The study contributes to literature by demonstrating (1) the impact of PCB on TI and (2) that POS explains why the strength of the positive relationship between PCB and TI varies among individuals. Results highlight the importance of fulfilling obligations and promises made by supervisors and managers to nurses. The findings suggest that when nurses with high POS perceive PCBs, the consequences may be more detrimental.
La ludification de l’existence, c’est-à-dire l’application d’une structure ludique dans nos vies, a été critiquée par C.Thi Nguyen dans Games: Agency as Art (2020). Cette critique illustre en quoi les relations présentées dans l’émission de téléréalité Occupation double sont des exemples de ludification de l’amour. Ces relations constituent des modèles trop simplifiés de ce qui fonde, selon Hichem Naar, les raisons d’aimer quelqu’un, lesquelles combinent certaines qualités de la personne et la manière dont celles-ci se manifestent dans la relation. Ultimement, la ludification des relations dans cette émission ne permet pas de développer une forme d’amour appropriée et durable.
Although social anxiety remains prevalent, conventional exposure therapy faces limitations such as limited accessibility, high cost, and low ecological validity. These barriers highlight the need for alternative, scalable methods that can effectively simulate social evaluative contexts.
Objective:
This study aims to evaluate the anxiety-inducing effects of videoconferencing exposure, measured through heart rate variability (HRV), using a fully online-based methodology.
Methods:
A total of 31 participants who reported social anxiety were recruited online and engaged in a simulated videoconference task, where they interacted with multiple audience members’ emotional faces on a 3 × 3 split screen. Their video recordings were analysed using imaging photoplethysmography to obtain HRV data. Baseline anxiety levels were assessed using validated self-report questionnaires, including the State Anxiety Scale (STAI-X1), Trait Anxiety Scale (STAI-X2), Social Interaction Anxiety Scale, and Social Phobia Scale.
Results:
Pearson correlation analysis revealed that STAI-X1 scores negatively correlated with high-frequency normalised units (HFnu) changes and positively correlated with low-frequency high-frequency (LF–HF) ratio and low-frequency normalised units (LFnu) changes. Similar patterns were observed for STAI-X2. These findings suggest that higher levels of trait and state anxiety are associated with greater reductions in parasympathetic activity and increased sympathetic activation during online videoconferencing.
Conclusions:
This study underscores the clinical potential of online videoconferencing as a scalable and accessible exposure therapy for the digital era, eliminating spatial and logistical constraints associated with traditional in-person exposure therapy.
Easily accessible, impactful, evidence-based resources are needed to assist mental health workers to best support voice-hearers in managing and living well with voices. Let’s Talk About Voices (LTAV) is an innovative suite of resources designed for mental health workers to use in supporting voice-hearers.
Aim
This study aimed to assess the impact of LTAV on mental health workers’ self-reported capacity to work with voice-hearers.
Method
A randomised, controlled crossover design was used, with assessment at three time points. The assessment measure was co-developed by researchers, clinicians, peer workers and voice-hearers based on the aims of LTAV and the Theory of Planned Behaviour. Participants were randomised into two groups. The immediate group received access to LTAV following the first assessment; the delayed group received access following the second assessment. In total, 256 mental health workers commenced the study, with 120 completing all assessments.
Results
Between-group comparisons for change between times 1 and 2 found a significant difference with a large effect size (F = 40.2, P < 0.001, ηp2 = 0.19). Significance remained on intention-to-treat analysis (F = 22.9, P < 0.001, ηp2 = 0.08). Pairwise repeated-measures comparisons found a significant increase in scores for both groups following access to LTAV, which was sustained at follow-up. Fourteen of 24 individual items showed significant change. Changes were consistent across professions, work settings and experience working with voice-hearers, but those with less confidence in working with voice-hearers on intake showed significantly stronger improvements.
Conclusions
This research indicates that LTAV has the potential to substantially improve mental health workers’ attitudes and confidence in supporting voice-hearers.
Workplace bullying is a persistent issue despite extensive research, with most studies focusing on targets rather than managerial perspectives. This study explores how New Zealand managers conceptualize workplace bullying, shedding light on cultural and organizational influences. While bullying affects roughly one in 10 New Zealand workers, definitions remain inconsistent, complicating prevention and response efforts. This research investigates whether managers distinguish bullying from other forms of conflict and aggression, and how their views align with regulatory definitions such as those from WorkSafe New Zealand. A randomized Qualtrics panel of 316 managers completed an anonymous online survey, including open-ended questions. Responses were analysed using six-phase thematic analysis, enabling candid reflection and rich insights into bullying behaviours, impacts, and organizational dynamics. The findings highlight the importance of understanding bullying within its communication context and suggest that clearer, less stigmatized definitions may support more effective reporting and intervention by managers.
Improving Access to Psychological Therapies (IAPT), an NHS England service providing talking therapies, is meeting its target recovery rate of 50%. However, engagement in treatment, as well as recovery rates, may be lower for some groups.
Aims
To assess variation in treatment completion and recovery rates by demographic and socioeconomic group and to describe rates of further referrals for patients to IAPT and secondary mental health services.
Method
Using 121 548 administrative records for 2019–2020 and 2022–2023 for the Norfolk and Waveney area, we estimated associations of age, gender, ethnicity and deprivation with the likelihood of treatment completion and recovery using logistic regression modelling. We also described rates of further referrals.
Results
Younger people and those living in deprived areas were less likely to recover or complete treatment, with those aged 16–17 years (n = 735) having the lowest adjusted odds for recovery (adjusted odds ratio = 0.5, 95% CI: 0.5–0.6) compared with those aged 36–70 years, and those aged 18–24 years (n = 23 563) having the lowest rate of completion (adjusted odds ratio = 0.5, 95% CI: 0.5–0.6). Further referrals before April 2022 were recorded for 45.4% of 6513 patients who had completed treatment and 68.8% of 9469 who had not completed treatment, and for 39.4% of 2007 recovered patients in 2019–2020 and 53.1% of 1586 who had not recovered. Non-completers had relatively more further referrals to secondary mental health services compared with completers (43.6% v. 22.8%; P < 0.01).
Conclusions
Younger people and those living in deprived areas have lower recovery and completion rates. Those who have completed treatment and not recovered have higher rates of further referrals.
Children born very preterm (VPT; ≤32 weeks’ gestation) are at higher risk of developing behavioural problems, encompassing socio-emotional processing and attention, compared to term-born children. This study aimed to examine multi-dimensional predictors of late childhood behavioural and psychiatric outcomes in very preterm children, using longitudinal clinical, environmental, and cognitive measures.
Methods
Participants were 153 VPT children previously enrolled in the Evaluation of Preterm Imaging study who underwent neuropsychological assessments at 18–24 months, 4–7 years and 8–11 years as part of the Brain Immunity and Psychopathology following very Preterm birth (BIPP) study. Predictors of late childhood behavioural and psychiatric outcomes were investigated, including clinical, environmental, cognitive, and behavioural measures in toddlerhood and early childhood. Parallel analysis and exploratory factor analysis were conducted to define outcome variables. A prediction model using elastic-net regularisation and repeated nested cross-validation was applied to evaluate the predictive strength of these variables.
Results
Factor analysis revealed two key outcome factors in late childhood: externalising and internalising-socio-emotional problems. The strongest predictors of externalising problems were response inhibition, effortful control and internalising symptoms in early childhood (cross-validated R2=.256). The strongest predictors of internalising problems were autism traits and poor cognitive flexibility in early childhood (cross-validated R2=.123). Cross-validation demonstrated robust prediction models, with higher accuracy for externalising symptoms.
Conclusions
Early childhood cognitive and behavioural outcomes predicted late childhood behavioural and psychiatric outcomes in very preterm children. These findings underscore the importance of early interventions targeting cognitive development and behavioural regulation to mitigate long-term psychiatric risks in very preterm children.
This article examines the development and transformation of Ukrainian scientific terminology during the early 20th century, particularly under Soviet rule. It traces the roots of terminological efforts in the 19th century, when language planning in Galicia and Ukraine reflected competing imperial influences and nationalist aspirations. The study underscores the nexus of cultural, political and epistemic interests in the shaping of scientific language, noting the transition from vernacular-focused Romantic ideals to the evolving policies of the Soviet korenizatsiia period.
In the 1920s, the Ukrainian Institute for Scientific Language led the effort to standardise terminology, aligning with Soviet policies of Ukrainisation/korenizatsiia. However, by the 1930s, Stalinist policies reversed earlier gains, replacing national vocabularies with Russified terms and persecuting many language policymakers and scholars that the Soviet regime had supported only a few years earlier.
People with opioid use disorder (OUD) have substantially higher standardised mortality rates compared with the general population. However, lack of individualised prognostic information presents challenges in personalisation of addiction treatment delivery.
Aims
To develop and validate the first prognostic models to estimate 6-month all-cause and drug-related mortality risk for people diagnosed with OUD using indicators recorded at baseline assessment in addiction services in England.
Method
Thirteen candidate prognostic variables, including sociodemographic, injecting status and health and mental health factors, were identified from nationally linked addiction treatment, hospital admission and death records from 1 April 2013 to 1 April 2022. Multivariable Cox regression models were developed with a fractional polynomial approach for continuous variables, and missing data were addressed using multiple imputation by chained equations. Validation was undertaken using bootstrapping methods. Discrimination was assessed using Harrel’s C and D statistics alongside examination of observed-to-predicted event rates and calibration curve slopes.
Results
Data were available for 236 064 people with OUD, with 2427 deaths due to any cause, including 1289 due to drug-related causes. Both final models demonstrated good optimism-adjusted discrimination and calibration, with all-cause and drug-related models, respectively, demonstrating Harrell’s C statistics of 0.73 (95% CI 0.71–0.75) and 0.74 (95% CI 0.72–0.76), D-statistics of 1.01 (95% CI 0.95–1.08) and 1.07 (95% CI 0.98–1.16) and calibration slopes of 1.01 (95% CI 0.95–1.08) and 1.01 (95% CI 0.94–1.10).
Conclusions
We developed and internally validated Roberts’ OUD mortality risk, with the first models to accurately quantify individualised absolute 6-month mortality risks in people with OUD presenting to addiction services. Independent validation is warranted to ensure these models have the optimal utility to assist wider future policy, commissioning and clinical decision-making.
This article explores the interaction between the Conseil de la Concurrence (Competition Council) and the Autorité de Régulation de la Poste et des Communications Électroniques (Telecommunications and Postal Regulatory Authority) (ARPCE) in the Algerian legal system. Algerian policy-makers have given special consideration to the issue of overlapping jurisdiction between these two authorities. The article discusses the Algerian strategy to resolve regulatory overlaps in the electronic communications market and also highlights the intervention of the ARPCE as a competition authority for the electronic communications market. Furthermore, the article analyses the Optimum Telecom Algeria case as a turning point in restoring the Competition Council’s role and highlights the need for systematizing the intervention of the two authorities. Finally, the article provides a forward-looking perspective through proposing a memorandum of understanding to promote cooperation between the Competition Council and the ARPCE.
Sense of humor is a universal human trait, enjoyed daily across cultures. However, little is known about the factors that shape individual differences in humor, particularly what contributes to developing a great sense of humor. While previous studies have identified a significant genetic component for various humor attributes, such as humor appreciation and humor styles, no study has looked at the heritability of humor production ability. This study is the first to assess the genetic and environmental influences on humor production ability using a twin study design. Participants included 448 pairs of monozygotic twins and 196 pairs of dizygotic twins (median age 66 years, mostly female) from the Twins UK registry. Twins self-assessed their humor ability, rated the funniness of their co-twin, and completed an objective humor production task by composing funny captions for captionless cartoons. Additionally, they completed a short cognitive ability test and reported their overall health. Findings revealed that self-rated humor ability was influenced by both additive genetic and nonshared environmental factors. In contrast, objective humor production showed no evidence of additive genetic effects. Instead, all individual differences were shaped by shared and nonshared environmental influences, though a small genetic effect cannot be ruled out. These results suggest that humor production may be more complex and difficult to assess than other cognitive abilities. The study also presents intriguing implications for the evolutionary basis of humor.
