AbstractGlacier phototroph blooms on the surfaces of ice sheets and glaciers cause albedo reduction, leading to increased melting rates. We observed seasonal changes in the abundance of phototrophs on the Qaanaaq Ice Cap in northwestern Greenland from June to August 2014, and reproduced these changes using numerical and empirical models. The phototroph community on the ice surface mainly consisted of the glacier algaAncylonema nordenskioldiiand the cyanobacteriumPhormidesmis priestleyi. The glacier alga appeared on the ice surface in late June, after which its abundance increased exponentially throughout the melting period. A logistic growth model designed for snow algal growth reproduced the measured exponential increases, suggesting that growth could be explained using the model as a function of the ice melting duration. Cyanobacteria appeared and their abundance increased in late July but did not change exponentially thereafter. The abundance of cyanobacteria was explained with an empirical model expressed as a function of the amount of mineral dust on the bare ice surface. Our numerical and empirical models for reproducing glacier algae and cyanobacteria could be useful for quantifying the albedo reduction caused by their growth and the melt rates of the Greenland ice sheet and glaciers in the future.

AbstractHigh Mountain Asia (HMA) glaciers are critical water reserves for montane regions, which are readily influenced by climate change. The glacier mass balance during 2000–2021 over HMA was estimated by comparing the elevations from ICESat-2 and the NASADEM. Radar penetration depth could be one of the intrinsic error sources in estimating glacier mass balance by using NASADEM. Therefore, we doubled elevation differences between the X-band Shuttle Radar Topography Missions (SRTMs) and NASADEM to estimate the potential error. The spatial characteristics of the altitude-dependent penetration depth can be detected in most sub-regions of HMA. Relatively deep penetrations in the Himalaya (2.3–3.7 m) and Hissar Alay (4.3 m) regions and small penetrations in the south-eastern HMA (1.0 m) were observed. The HMA region experienced a significant mass loss at a rate of −0.18 ± 0.12 m w.e. a−1, in which the Hengduan Shan exhibited the highest mass loss of −0.62 ± 0.10 m w.e. a−1, the West Kun Lun experienced a substantial mass gain of 0.23 ± 0.13 m w.e. a−1, and the Karakoram showed a more or less balance. Our results are in agreement with previous studies that assessed the mass balance of HMA glaciers from different methods.
On the study of the running maximum and minimum level of level-dependent quasi-birth–death processes and related models
Authors: Javier Kayla , Fralix Brian 
Published: September 2022

AbstractWe present a study of the joint distribution of both the state of a level-dependent quasi-birth–death (QBD) process and its associated running maximum level, at a fixed time t: more specifically, we derive expressions for the Laplace transforms of transition functions that contain this information, and the expressions we derive contain familiar constructs from the classical theory of QBD processes. Indeed, one important takeaway from our results is that the distribution of the running maximum level of a level-dependent QBD process can be studied using results that are highly analogous to the more well-established theory of level-dependent QBD processes that focuses primarily on the joint distribution of the level and phase. We also explain how our methods naturally extend to the study of level-dependent Markov processes of M/G/1 type, if we instead keep track of the running minimum level instead of the running maximum level.
Remembering the Causes of Collective Violence and the Role of Propaganda in the Yugoslav Wars
Authors: Kiper Jordan 
Published: September 2022

AbstractLegal narratives about collective violence have given an outsized explanatory role to propaganda in conflicts such as the Rwandan genocide and the Yugoslav Wars. While post-conflict ethnographies have examined what Rwandans remember about propaganda and collective violence, similar studies have not been undertaken in territories of the former Yugoslavia. The present ethnographic study fills this gap. After introducing the theoretical and empirical problems that have stemmed from recent speech crime trials in international criminal law, I examine the causes of collective violence in the Yugoslav Wars as remembered by former combatants, survivors, and the greater populations of post-conflict regions in Bosnia-Herzegovina, Croatia, and Serbia. I show that remembered causes, including the role of propaganda, vary significantly between former combatants and the greater populations. Nevertheless, local perspectives, especially among former combatants and survivors, converge on the effects of populist movements following Yugoslavia’s economic crisis and the rise of ethnic, religious, and nationalist leaders who engaged in inflammatory rhetoric and misinformation to mobilize war efforts. This article thus corroborates key findings from other post-conflict ethnographies which show that propaganda plays a secondary but significant role in the cultural manufacturing of state-sponsored ethnicity and cultural logics of violence.

AbstractWe present the first observational study of pulsars performed with the second-generation precursor stations to the low-frequency component of the Square Kilometre Array (SKA-Low): the Aperture Array Verification System 2 (AAVS2) and the Engineering Development Array 2 (EDA2). Using the SKA-Low stations, we have observed 100 southern-sky pulsars between 70–350 MHz, including follow-up observations at multiple frequencies for a selected sample of bright pulsars. These observations have yielded detections of 22 pulsars, including the lowest-frequency detections ever published for 6 pulsars, despite the modest sensitivity of initial system where the recording bandwidth is limited to${\sim}{1}\,\mathrm{MHz}$. By comparing simultaneous flux density measurements obtained with the SKA-Low stations and performing rigorous electromagnetic simulations, we verify the accuracy of the SKA-Low sensitivity simulation code presented in Sokolowski (2022, PASA, 39, e015). Furthermore, we perform model fits to the radio spectra of the detected pulsars using the method developed by Jankowski (2018, MNRAS, 473, 4436), including nine pulsars which were not fitted in the original work. We robustly classify the spectra into five morphological classes and find that all but one pulsar exhibit deviations from simple power-law behaviour. These findings suggest that pulsars with well-determined spectra are more likely to show spectral flattening or turnover than average. Our work demonstrates how SKA-Low stations can be meaningfully used for scientifically useful measurements and analysis of pulsar radio spectra, which are important inputs for informing pulsar surveys and science planned with the SKA-Low.
What It Means to Have Nothing: Poverty and the Idea of Human Dignity in Nineteenth-Century Germany
Authors: Althammer Beate 
Published: September 2022

AbstractThis article explores the historical background of an issue that is central to present-day constitutional and human-rights discourse: the relationship between human dignity and the fight against poverty. It analyzes the role the idea of human dignity played in the reasoning of nineteenth-century German middle-class authors who were professionally engaged in social-reform debates, with a particular focus on debates about mendicancy. In these debates, notions of dignity were pervasive, and they provoked a troubling question: Is poverty a state of impaired dignity, and if yes, in which direction does causality point? Tracing the shifting perceptions from the enlightened belief in the self-perfectibility of man at the beginning of the nineteenth century to the rise of biomedical theories at its end, the article argues that concerns about human dignity gave the commitment to eradicate destitution an important impetus, yet with side effects that highlight the pitfalls of the dignity concept.
Child Assistance and the Making of Modern Refugee Camps in Austria-Hungary during the First World War
Authors: Cretu Doina Anca 
Published: September 2022

AbstractThis article explores the development of modern refugee camps in Austria-Hungary during the First World War by looking at the organization and implementation of child assistance in the camps. The article argues that a state-driven mobilization of relief and rehabilitation was organized to alleviate the plight of refugee children. It points particularly to children's health care and the organization of education as instances that marked a shift in the scope of refugee camps in wartime Austria-Hungary. At first, camps represented a temporary measure to immobilize and control displaced populations. As the war progressed, they became a permanent feature of refugee policy and a microcosm of agendas of state consolidation. Ultimately, the case of child assistance shows that the organization of refugee camps in wartime Austria-Hungary was a fluid and gradual process that meshed technologies of population containment with humanitarian and welfare practices.

AbstractBackgroundPsychotic experiences (PEs) frequently occur and are associated with a range of negative health outcomes. Prospective studies on PEs are scarce, and to date no study investigated PE prevalence, incidence, persistence, their risk indicators, and psychiatric comorbidity, in one dataset. Furthermore, most studies are based on self-report, and it is unclear how this compares to clinical interviews.MethodsData are used from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2), a psychiatric cohort study among a representative sample of adults (baseline characteristics: N = 6646; 49.6% female; 18–64 years). Results are presented for self-reported and clinically validated PEs. Associations are assessed for mental disorders, socio-demographic, vulnerability, physical health, and substance use factors.ResultsBased on self-report, at baseline 16.5% of respondents had at least one PE in their lifetime, of those, 30.1% also reported a PE at 3-year follow-up. 4.8% had a first PE at 3-year follow up. The 3-year prevalence of PE was associated with almost all studied risk indicators. Generally, the strongest associations were found for mental health disorders. Prevalence and incidence rates were two to three times higher in self-report than in clinical interview but results on associated factors were similar.ConclusionsValidated prevalence and incidence estimates of PE are substantially lower than self-reported figures but results on associated factors were similar. Therefore, future studies on associations of PEs can rely on relatively inexpensive self-reports of PEs. The associations between PE and mental disorders underline the importance of assessment of PE in general practice.
Challenges to the Strategic State: Welfare Reform Lessons from a Devolved Polity
Authors: SINCLAIR STEPHEN 
Published: September 2022

AbstractThe article critically examines the Strategic State approach to social policy as represented by the ‘Scottish Approach’ to policy-making and delivery. The article outlines the defining features of a strategic approach to social policy and critically appraises the Scottish Government’s claim to reflect these principles in flagship welfare reforms. The article considers how far a strategic policy approach has been applied in Scotland and draws upon research exploring the response of local leaders to the challenges posed by the COVID-19 pandemic to examine what this experience reveals about how ‘strategic’ these actions were. The article concludes that, in contrast to previous slow progress in implementing a strategic approach, the exigencies of COVID compelled innovations in policy making and accelerated practices consistent with a strategic approach. The article concludes with some reflections on what this evidence implies for strategic social policy making and governance.

AbstractTechnological interventions are increasingly popular methods of targeting and preventing loneliness in older adults. Research has identified various factors that influence the willingness and propensity of older adults to integrate technology into their social lives and the ways in which this may enhance their social connectedness. Given prevalence rates and negative outcomes associated with loneliness for this population, further research is warranted to clarify the mechanisms through which technological interventions may decrease loneliness. This study aimed to better understand the perspectives of older adults on the role of technology in their social relationships in later life. Four focus groups were conducted with 27 older adults, aged 65–80 years. Transcripts were analysed using thematic analysis, and results were validated via written participant feedback. Participants reported technology as one of many tools used to maintain their social relationships. Their choice to use technology for social interaction was influenced by their estimation of effort required, likely quality of the interaction, and the privacy and security provided. These factors were the same as those that influenced decisions to use other methods (e.g. face-to-face meetings). Based on the results, we recommend that loneliness interventions should be technology-agnostic and multifaceted, providing a wide range of tools that recognise the technological competencies of older adults and supporting different interaction types to meet the preferences of the individual.
The experiences of grandparents looking after their grandchildren: examining feelings of burden and obligation among non-custodial grandparents
Authors: Grünwald Olga , Damman Marleen , Henkens Kène 
Published: September 2022

AbstractQuantitative research on how grandparents fare when looking after grandchildren has mainly focused on general wellbeing indicators, showing that grandparenting is linked to higher wellbeing. However, global assessments of wellbeing reveal little about activity-specific experiences and only indirectly provide insights about how grandparents experience grandchild care. Whereas qualitative studies have observed diversity in grandparenting experiences, quantitative insights regarding potential strains of grandparenting are scarce. This study examines directly to what extent grandparents experience supplementary grandchild care as burdensome and obligatory, and tests – building on role strain theory – how differences in grandparents' characteristics can explain these experiences. Analyses are based on data collected in 2015 and 2018 among 3,429 Dutch grandparents who look after grandchildren. Descriptive findings show that 20 per cent of the studied grandparents experienced grandparenting as fairly/very burdensome and 8 per cent as fairly/very obligatory. Ordinal logistic regression models with random effects show that more-intense grandparenting situations were linked to higher levels of burden and obligation. Moreover, grandparents in poor health, higher education and those with other responsibilities (e.g. paid work) were relatively more likely to experience higher levels of burden and obligation. Our findings imply that the understanding of non-custodial grandparenting as only rewarding might be one-sided, as positive and negative experiences can go together. There appears to be substantial heterogeneity in how grandparents experience looking after their grandchildren.
Indexed and fibered structures for partial and total correctness assertions

Published: September 2022

AbstractHoare Logic has a long tradition in formal verification and has been continuously developed and used to verify a broad class of programs, including sequential, object-oriented, and concurrent programs. Here we focus on partial and total correctness assertions within the framework of Hoare logic and show that a comprehensive categorical analysis of its axiomatic semantics needs the languages of indexed and fibered category theory. We consider Hoare formulas with local, finite contexts, of program and logical variables. The structural features of Hoare assertions are presented in an indexed setting, while the logical features of deduction are modeled in the fibered one.

Abstract
Since embryonic stem cells (ESCs) were first identified, significant progress has been achieved. However, the establishment of buffalo ESCs (bESCs) is still unclear. This study was undertaken to explore the effect of the blastocyst stage on the isolation of bESCs. Firstly, our results indicated that the pluripotent genes were mainly expressed at the early stages of blastocyst, and the attachment and colony formation rates of bESCs derived from expanded blastocyst and hatched blastocyst were significantly higher than early blastocyst and blastocyst. In the meantime, bESCs showed positive alkaline phosphatase activity and expressed genes like OCT4, NANOG, SOX2, c-MYC, CDH1, KLF4, and TBX3. Immunofluorescence also confirmed the expression of OCT4, SOX2. Embryoid bodies expressing three marker genes were generated from the differentiation experiment, and fibroblast, epithelial, and neuron-like cells were induced. Moreover, naive-related genes KLF4, TBX3, primed-related genes FGF5, ACTA2 were expressed in the cells, but not REX-1. Immunofluorescence and western blot confirmed the FGF5 expression. Furthermore, bESCs could maintain pluripotency with the signal of LIF and bFGF. In summary, our results indicated that expanded blastocyst and hatched blastocyst are more suitable for bESCs isolation.
Any lessons to learn? Pathways and impasses towards health system resilience in post-pandemic times
Authors: Ewert Benjamin , Wallenburg Iris , Winblad Ulrika , Bal Roland 
Published: September 2022

AbstractThe COVID-19 pandemic has been an ultimate challenge for health systems as a whole rather than just single sectors (e.g. hospital care). Particularly, interface management between health system sectors and cooperation among stakeholders turned out to be crucial for an adequate crisis response. Dealing with such interfaces, it is argued in the literature, demands from health care systems to become resilient. One way to analyse this is to focus on the ways in which bottlenecks in health systems are dealt with during the pandemic. This paper investigates six bottlenecks, including overburdened public health agencies, neglected nursing homes and insufficient testing capacities that have been encountered in the health systems of Germany, Sweden and the Netherlands during the pandemic. Based on empirical findings we identify and critically discuss preliminary lessons in terms of health system resilience, an increasingly popular theoretical concept that frames crises as an opportunity for health system renewal. We argue that in practice health system resilience is hindered by path dependencies of national health systems and, owed to the crisis, interim policies that lack ambition for broader reforms.
Consumption Change‐Induced Transients in a Water Distribution Network: Laboratory Tests in a Looped System

Published: September 2022

AbstractAt the Water Engineering Laboratory of the University of Perugia, Italy, a wide experimental program has been carried out in a polymeric pipe network with two 100 × 100 m square loops. The aim of this program is to analyze the dynamic response of the system to transients caused by a change in water consumption. To emphasize such a response, transients are generated by the complete and fast closure of an end‐user, located at the downstream end of a service line. During tests, the combined effect of simultaneous consumers, whose consumption is varied both deterministically and stochastically, has been analyzed. The tests allow examining the propagation of the generated pressure waves within the network for different water consumption variations and end‐user locations. The lessons learnt from the experimental results may help the water utility managers to identify the reasons for the higher frequency of occurrence and severity of faults in some specific portions of water distribution networks apparently “similar” to others where damages are less frequent and severe.
Deep Learning for Simultaneous Inference of Hydraulic and Transport Properties
Authors: Zhou Zitong , Zabaras Nicholas , Tartakovsky Daniel M. 
Published: September 2022

AbstractIdentification of a heterogeneous conductivity field and reconstruction of a contaminant release history are key aspects of subsurface remediation. These two goals are achieved by combining model predictions with sparse and noisy hydraulic head and concentration measurements. Solution of this inverse problem is notoriously difficult due to, in part, high dimensionality of the parameter space and high computational cost of repeated forward solves. We use a convolutional adversarial autoencoder (CAAE) to parameterize a heterogeneous non‐Gaussian conductivity field via a low‐dimensional latent representation. A three‐dimensional dense convolutional encoder‐decoder (DenseED) network serves as a forward surrogate of the flow and transport model. The CAAE‐DenseED surrogate is fed into the ensemble smoother with multiple data assimilation (ESMDA) algorithm to sample from the Bayesian posterior distribution of the unknown parameters, forming a CAAE‐DenseED‐ESMDA inversion framework. The resulting CAAE‐DenseED‐ESMDA inversion strategy is used to identify a three‐dimensional contaminant source and conductivity field. A comparison of the inversion results from CAAE‐ESMDA with physical flow and transport simulator and from CAAE‐DenseED‐ESMDA shows that the latter yields accurate reconstruction results at the fraction of the computational cost of the former.
