This study explores the experiences of Russian relocants in Turkey, focusing on their migration trajectories through overlapping waves of shock, relocation, and partial mobilization, following the Russian invasion of Ukraine in 2022. Initially, Turkey was an attractive destination due to its visa-free access, air connectivity, affordable cost of living, and established post-Soviet community. However, among the nearly one million people who fled Russia, many relocants – primarily young, educated, and entrepreneurial individuals from the information technology sector and oppositional groups – face various uncertainties in Turkey. Drawing on findings from a qualitative study, this research first examines the migration journeys of Russian relocants through their self-narratives, tracing the waves of the exodus in 2022. It then critically analyzes the legal, economic, and social uncertainties they encounter in Turkey. Finally, it explores how the physical and virtual “bubbles” formed in İstanbul function as coping mechanisms to navigate these challenges. Blending staying and returning, bubbles function as temporary “in-between” spaces, allowing Russian relocants to encounter Turkey’s novelties, while maintaining a “transnational double presence” through ongoing ties to their homeland, resulting in a form of “functional adaptation.”
The green transition to reduce greenhouse gas emissions requires substantial investments in a narrow time window to avoid climate-related disruptions, adding two new dimensions for monetary policy and exacerbating the trade-offs that central banks face. First, climate-related physical disruptions lead to higher inflation (i.e., Climateflation). Second, the rush to green technology may result in inflation due to supply bottlenecks (i.e., Greenflation). As a consequence, central banks implement restrictive monetary policy that have a detrimental effect on the high up-front costs of renewable energy projects. This slows down the dynamics of green technologies adoption. We build a dynamic non-linear model to study these interactions under reasonable parameterizations. Both Climateflation and Greenflation are quantitatively significant, creating a dilemma for central banks between raising interest rates to counteract inflation and easing them to facilitate renewable investment. We further show that, under specific stochastic scenarios, the trade-off between inflation control and green transition can improve when structural costs for green technologies decrease or when supply-side constraints relax.
In this paper, we give a complete, two-way characterization, of when a noncommutative crossed product $A \rtimes_\lambda G$ is simple, in the case of G being an FC-hypercentral group. This is a large class of amenable groups that contains all virtually nilpotent groups, and in the finitely generated setting, coincides with the set of groups which have polynomial growth. We further completely characterize the ideal intersection property under the assumption that the group is FC, meaning that every element has a finite conjugacy class. Finally, for minimal actions of arbitrary discrete groups on unital C*-algebras, we are able to characterize when the crossed product $A \rtimes_\lambda G$ is prime.
Despite increasing awareness and understanding of children’s victimisation through experiences of domestic violence (EDV), little attention has been given to the associated health outcomes.
Aim
Examine associations between four different forms of childhood EDV (physical violence, threats of harm, property damage and intimidation or control) and four mental disorders and six health risk behaviours.
Method
Data were drawn from the Australian Child Maltreatment Study. Associations were examined using survey-weighted logistic regression models. Estimates were calculated adjusting for each other form of EDV, as well as other types of child maltreatment and socio-economic factors. Each model was stratified for men and women.
Results
All mental disorders and health risk behaviours were more common among those with any childhood EDV compared to those without. Intimidation or control and damage to property or pets independently predicted most mental disorders and health risk behaviours. The strongest association was found between intimidation or control and post-traumatic stress disorder (adjusted odds ratio (aOR) 2.30, 95% CI 1.77–2.98) and generalised anxiety disorder (aOR 1.65, 95% CI 1.36–1.99), and damage to property or pets and severe alcohol use disorder (aOR 1.76, 95% CI 1.36–2.27).
Conclusions
Childhood EDV characterised by intimidation or control and property damage or harm to pets significantly increases the risk of mental disorders and health risk behaviours in adulthood. Urgent investment is needed in child-centred and trauma- and family-violence-informed interventions that support children’s recovery and stronger legal protections to prevent children from being weaponised in post-separation coercive control.
For decades researchers have called attention to the problem of bullying among children and adolescents in school. Starting in 1999, states began responding to this problem by promulgating anti-bullying laws. Although anti-bullying laws now exist in every state and the District of Columbia, a comprehensive review of those law has not been conducted in nearly ten years. White et al., have provided that update. Their work is significant on a number of fronts. Still, for all their good intentions and effects, the anti-bullying laws have limitations, arguably significant limitations.
The mother sporocyst is the least understood digenean life cycle stage. This study provides the first detailed description of the neuromusculature and reproductive apparatus of mother sporocysts in the hemiuroid digenean Bunocotyle progenetica, a monoxenous parasite of White Sea mud snails, using transmission electron microscopy and fluorescent staining for muscles, FMRFamide-related peptides (FaRP), and serotonin (5HT). These parthenitae lack a germinal mass and have only a few germinal elements, which explains their limited reproductive potential. Germinal cells are incorporated into the syncytial brood-cavity lining, asynchronously maturing and forming germinal balls, which develop into rediae within the cavity. Rediae are expelled through a birth canal differentiated into three regions; their expulsion involves coordinated action of circular sphincter muscles and several extrinsic muscles. Sporocysts are highly mobile, with a dense subtegumental network of circular and longitudinal muscles. Subtegumental myocyte reconstruction showed that each perikaryon is linked to several myofibrils. The nervous system, although lacking distinct ganglia, is well-differentiated, with numerous neurons and at least three types of tegumental sensilla. FaRP-immunoreactive (IR) somata surround the birth canal, forming a nerve net around its middle region and two posterior longitudinal nerves. The unusually abundant 5HT-IR neurons are distributed throughout the body, but most lie in the posterior region. 5HT-IR cells form an anterior nerve ring, from which several nerves project anteriorly and two main nerves extend posteriorly, along with additional nerves. The morphology of the studied sporocysts is discussed in the context of current knowledge on the parthenital biology and development in B. progenetica.
This article reads Sonny Liew’s graphic novel The Art of Charlie Chan Hock Chye (2015) as an expression and interlocutor of Ariella Aïsha Azoulay’s method of potential history. Thinking alongside Walter Benjamin’s media theory and philosophy of history, Azoulay reconceives the camera shutter as a material apparatus that executes the imperial violence of expelling, and making obsolete, the past from the present in the name of progress. Azoulay’s critical practice finds its artistic analog in Liew’s comic, which contests official accounts of Singapore’s pre-independence history by remediating archived photographs of the nation’s former politicians. My bilateral reading of Liew and Azoulay advances ‘potential legal history’ as an emerging methodological-theoretical perspective that orients legal scholars to photographs, graphic novels, and other visual-narrative forms as vital matters for the reimagining of national histories.
Risk-sharing rules have been applied to mortality pooling products to ensure these products are actuarially fair and self-sustaining. However, most of the existing studies on the risk-sharing rules of mortality pooling products assume deterministic mortality rates, whereas the literature on mortality models provides empirical evidence suggesting that mortality rates are stochastic and correlated between cohorts. In this paper, we extend existing risk-sharing rules and introduce a new risk-sharing rule, named the joint expectation (JE) rule, to ensure the actuarial fairness of mortality pooling products while accounting for stochastic and correlated mortality rates. Moreover, we perform a systematic study of how the choice of risk-sharing rule, the volatility and correlation of mortality rates, pool size, account balance, and age affect the distribution of mortality credits. Then, we explore a dynamic pool that accommodates heterogeneous members and allows new entrants, and we track the income payments for different members over time. Furthermore, we compare different risk-sharing rules under the scenario of a systematic shock in mortality rates. We find that the account balance affects the distribution of mortality credits for the regression rule, while it has no effect under the proportional, JE, and alive-only rules. We also find that a larger pool size increases the sensitivity to the deviation in total mortality credits for cohorts with mortality rates that are volatile and highly correlated with those of other cohorts, under the stochastic regression rule. Finally, we find that risk-sharing rules significantly influence the effect of longevity shocks on fund balances since, under different risk-sharing rules, fund balances have different sensitivities to deviations in mortality credits.
Lubricant viscoelasticity arises due to a finite polymer relaxation time ($\lambda$) which can be exploited to enhance lubricant performance. In applications such as bearings, gears, biological joints, etc., where the height-to-length ratio ($H_0 / \ell _x$) is small and the shear due to the wall velocity ($U_0$) is high, a simplified two-dimensional computational analysis across the channel length and height reveals a finite increase in the load-carrying capacity of the film purely due to polymer elasticity. In channels with a finite length-to-width ratio, $a$, the spanwise effects can be significant, but the resulting mathematical model is computationally intensive. In this work, we propose simpler reduced-order models, namely via (i) a first-order perturbation in the Deborah number ($\lambda U_0 / \ell _x$) and (ii) the viscoelastic Reynolds approach extended from Ahmed & Biancofiore (J. Non-Newtonian Fluid Mech., vol. 292, 2021, 104524). We predict the variation in the net vertical force exerted on the channel walls (for a fixed film height) versus increasing viscoelasticity, modelled using the Oldroyd-B constitutive relation, and the channel aspect ratio. The models predict an increase in the net force, which is zero for the Newtonian case, versus both the Deborah number and the channel aspect ratio. Interestingly, for a fixed $\textit{De}$, this force varies strongly between the two limiting cases (i) $a \ll 1$, an infinitely wide channel, and (ii) $a \gg 1$, an infinitely short channel, implying a change in the polymer response. Furthermore, we observe a different trend (i) for a spanwise-varying channel, in which a peak is observed between the two limits, and (ii) for a spanwise-uniform channel, where the largest load value is for $a \ll 1$. When $a$ is O($1$), the viscoelastic response varies strongly and spanwise effects cannot be ignored.
The limited efficacy of monotherapy and the insufficient clinical experience with triple therapy (levosimendan, dapagliflozin, and sacubitril/valsartan) warrant further investigation. The aim of this study was to evaluate the effects of triple therapy on left ventricular function in children with advanced heart failure whose left ventricular function had not improved despite classical heart failure treatment and who remained dependent on inotropes.
Methods:
The study included children who were admitted to the hospital with advanced heart failure and who were still inotrope-dependent at a mean of 42 days after the start of classical heart failure treatment and then started triple therapy at our hospital.
Results:
The study included 18 patients, 8 (44%) males, with a median age of 4 years (2–7 years). Before and after classical treatment and after triple treatment, statistically significant improvement in two-dimensional left ventricular ejection fraction (%) (median values 30; 38; 55, respectively), left ventricular end-diastolic diameter (median values 44; 45; 40 mm), left ventricular end-systolic diameter (median values 38; 36; 29 mm), left ventricular end-diastolic diameter (z score) (median values 4.2; 3.2; 2.7), left ventricular end-systolic diameter (z score) (median values 5.8; 4.8; 3.2), Simpson left ventricular ejection fraction (%) (median values 29; 36.5; 55), Simpson left ventricular end-diastolic volume (median values 60; 55; 43 ml), left ventricular end-systolic volume (median values 43; 40; 18. 5 ml), left ventricular global longitudinal strain four-chamber (median values -8.1;-10;-19), left ventricular global longitudinal strain three-chamber (median values -5.9;-8.9;-14), and left ventricular global longitudinal strain mean (median values -6.9;-9.7;-19) values was observed (all values p < 0.05).
Conclusions:
In children admitted to the hospital with advanced heart failure whose left ventricular function has not improved with classical therapy, it seems likely that both left ventricular systolic and diastolic function will improve, inotrope dependency will resolve, and patients can be discharged with the new triple drug therapy.
When areas of the law are ambiguous or untested, such as in the compassionate release cases that proliferated during the height of the COVID-19 pandemic, district judges must rely on their discretion to fill in legal gaps. Discretion can be beneficial, because it means that it allows district judges to consider factors that may lead to potentially harmful outcomes for litigants or their communities. But discretion is imperfect, particularly in the face of ethically or factually complex problems. Perhaps a place to start with addressing this difficulty is greater transparency about the benefits and limitations of discretion.
