Perceived Help and Support for Sex as Self-Injury: A Qualitative Study of a Swedish Sample
Authors: Fredlund Cecilia , Jonsson Linda S. 
Published: October 2022

AbstractEarlier research has found that sexual acts could be used as a means of self-injury, with comparable functions to nonsuicidal self-injury (NSSI) such as cutting or burning the skin. However, no previous study has investigated the experience of help and support in relation to sex as a means of self-injury (SASI), which this study aims to investigate. The study was based on an anonymous open-ended questionnaire published from December 2016 to April 2017 on the websites of NGOs working with help and support for women and youths in Sweden. In total, 197 participants (mostly women, mean age 27.9 years, range 15–64 years) with self-reported experiences of SASI were included in the study. Three main themes were found concerning experiences of help and support for SASI. The need for: (1) Framing the behavior of SASI, to find a word for SASI—to know it exists, to get questions and information about SASI and its function; (2) Flexible, respectful, and professional help and support from an early age, to be listened to and confirmed in one’s experience of SASI; and (3) Help with underlying reasons to exit SASI such as finding one’s own value and boundaries through conventional therapy, through life itself, or through therapy for underlying issues such as earlier traumatic events, PTSD, dissociation, or anxiety. In conclusion, similar interventions could be helpful for SASI as for NSSI, irrespective of the topographical differences between the behaviors, but the risk of victimization and traumatization must also be addressed in SASI.
The irreducible vectors of a lattice:

Published: October 2022

AbstractThe main idea behind lattice sieving algorithms is to reduce a sufficiently large number of lattice vectors with each other so that a set of short enough vectors is obtained. It is therefore natural to study vectors which cannot be reduced. In this work we give a concrete definition of an irreducible vector and study the properties of the set of all such vectors. We show that the set of irreducible vectors is a subset of the set of Voronoi relevant vectors and study its properties. For extremal lattices this set may contain as many as $$2^n$$

n

vectors, which leads us to define the notion of a complete system of irreducible vectors, whose size can be upper-bounded by the kissing number. One of our main results shows that modified heuristic sieving algorithms heuristically approximate such a set (modulo sign). We provide experiments in low dimensions which support this theory. Finally we give some applications of this set in the study of lattice problems such as SVP, SIVP and CVPP. The introduced notions, as well as various results derived along the way, may provide further insights into lattice algorithms and motivate new research into understanding these algorithms better.

AbstractOkhotsk or western gray whales feed in summer along the northeastern coast of Sakhalin Island, Russia, a region with oil and gas extraction facilities. Seismic surveys increased sound levels in the nearshore feeding area in 2015 for part of the summer, potentially displacing whales from preferred foraging habitat or reducing foraging efficiency. Since lost foraging opportunities might lead to vital rate effects on this endangered species, detailed benthic surveys were conducted to characterize benthic community biomass patterns and spatial and temporal differences. Benthic biomass demonstrated strong spatial–temporal interactions indicating that prey biomass differences among locations were dependent on sampling period. Of greatest interest, Amphipoda biomass declined from June to October in the northern and southern portions of the nearshore study area but increased in the middle and Actinopterygii biomass increased in the northern area in mid-summer. Water depth and sediment type were significant covariates with community structure, and water depth strongly covaried with bivalve biomass. Total average prey biomass was ~ 100 g/m2within the nearshore feeding area with no evidence of reduced biomass among sampling periods or locations, although there were fewer amphipods in the south. Multi-prey investigations provide a stronger basis for inferences than single-prey studies of amphipods when gray whales feed on diverse prey. Benthic community-level variability was moderate to high as would be expected for a shallow-water nearshore area. Overall, spatial and temporal changes in dominant macrofauna biomass reflected small to medium-sized effects that were well within the natural boundaries expected for benthic communities.
Benthic studies adjacent to Sakhalin Island, Russia 2015 III: benthic energy density spatial models in the nearshore gray whale feeding area

Published: October 2022

AbstractEnergy densities of six dominant benthic groups (Actinopterygii, Amphipoda, Bivalvia, Cumacea, Isopoda, and Polychaeta) and total prey energy were modeled for the nearshore western gray whale feeding area, Sakhalin Island, Russia, as part of a multi-disciplinary research program in the summer of 2015. Energy was modeled using generalized additive mixed models (GAMM) with accommodations for zero-inflation (logistic regression and hurdle models) and regression predictions combined with kriging to interpolate energy densities across the nearshore feeding area. Amphipoda energy density was the highest nearshore and in the south whereas Bivalvia energy density was the highest offshore and in the northern portion of the study area. Total energy was the highest in mid-range distances from shore and in the north. Amphipoda energy density was higher than minimum energy estimates defining gray whale feeding habitats (312–442 kJ/m2) in 13% of the nearshore feeding area whereas total prey energy density was higher than the minimum energy requirement in 49% of the habitat. Inverse distance-weighted interpolations of Amphipoda energy provided a broader scale representation of the data whereas kriging estimates were spatially limited but more representative of higher density in the southern portion of the study area. Both methods represented the general trend of higher Amphipoda energy density nearshore but with significant differences that highlight the value of using multiple methods to model patterns in highly complex environments.

Published: October 2022

AbstractGray whales utilizing their foraging grounds off northeastern Sakhalin Island, Russia, have been increasingly exposed to anthropogenic activities related to oil and gas development over the past two decades. In 2015, four seismic vessels, contracted by two operators, conducted surveys near and within the gray whale feeding grounds. Mitigation and monitoring plans were developed prior to the survey and implemented in the field, with real-time data transfers to assist the implementation of measures aimed at minimizing impacts of acoustic exposure. This study examined the behavioral response of gray whales relative to vessel proximities and sounds generated during seismic exploration. Five shore-based teams monitored gray whale behavior from 1 June to 30 September using theodolite tracking and focal follow methodologies. Behavioral data were combined with acoustic and benthic information from studies conducted during the same period. A total of 1270 tracks (mean duration = 0.9 h) and 401 focal follows (1.1 h) were collected with gray whales exposed to sounds ranging from 59 to 172 dB re 1 μPa2SPL. Mixed models were used to examine 13 movement and 10 respiration response variables relative to “natural,” acoustic, and non-acoustic explanatory variables. Water depth and behavioral state were the largest predictors of gray whale movement and respiration patterns. As vessels approached whales with increasing seismic/vessel sound exposure levels and decreasing distances, several gray whale movement and respiration response variables significantly changed (increasing speed, directionality, surface time, respiration intervals, etc.). Although the mitigation measures employed could have reduced larger/long-term responses and sensitization to the seismic activities, this study illustrates that mitigation measures did not eliminate behavioral responses, at least in the short-term, of feeding gray whales to the activities.
Sustainability gap of public debt: importance of interest rates and a new decomposition with premia
Authors: Dönnebrink Elmar , Grevenbrock Nils 
Published: October 2022

AbstractSustainability gaps (S2 indicators) are frequently used in national and international reports to assess the sustainability of public finances. For instance, in the European Commission’s Debt Sustainability Monitor (DSM) the indicators are analyzed in comparisons across (policy) scenarios, countries and time. The report’s findings play a crucial role in the context of the Stability and Growth Pact and the European Semester. As a result, sustainability gaps have a significant indirect influence on policy decisions. In this paper, we analyze two non-transparent properties of these indicators. First, the response of these indicators to changes in the interest rate-growth (r-g) differential is not readily predictable in terms of both strength and direction. Second, in our examples for low values of r-g (in a range of 0.5%), highly uncertain projections for distant periods after 2070 explain about 80% of the indicators’ values. To address these problems, we develop a new decomposition that takes into account the notion of premia (Reis 2021) and hence allows for a more transparent discussion of the sustainability of public debt.
Mycorrhizal symbiosis-induced abiotic stress mitigation through phosphate transporters in Solanum lycopersicum L

Published: October 2022

AbstractArbuscular mycorrhizal (AM) symbiosis and abiotic stress mitigation have intrigued researchers for more than a century, but how different phosphate transporters, such as members of the Pht1 gene family, are influenced during the combined presence of AM fungi and stress is not well known. In this study, the impact of AM fungi (Funneliformis mosseae) on tomato plants under water deficit and heat stress was investigated via observing the physiological changes and applying spectrophotometric and quantitative real-time PCR methods, with a focus on phosphate transporters (Pht1;1, Pht1;3, Pht1;4, Pht1;6, Pht1;7 and Pht1;8). Moreover, genes encoding heat-responsive proteins (HSFA2 and HSP70) and aquaporins (PIP2.5 and PIP2.7) were also studied. On the basis of our results, AM fungi seemingly mitigated heat and combined (heat and water deficit) stresses through the mediation of the expression of Pht1 family phosphate transporter genes. In addition to the Pht1;3 and Pht1;4 genes, Pht1;7 also seems to be an AM fungus-inducible phosphate transporter gene. The results of this study may provide insights into the behavior of phosphate transporter gene family members and a potential strategy to enhance the vigor of tomato plants through increased phosphorous uptake under heat stress, water deficit and heat and water deficit combined.
Does conflict of interest distort global university rankings?
Authors: Chirikov Igor 
Published: October 2022

Abstract
Global university rankings influence students’ choices and higher education policies throughout the world. When rankers not only evaluate universities but also provide them with consulting, analytics, or advertising services, rankers are vulnerable to conflicts of interest that may potentially distort their rankings. The paper assesses the impact of contracting with rankers on university ranking outcomes using a difference-in-difference research design. The study matches data on the positions of 28 Russian universities in QS World University Rankings between 2016 and 2021 with information on contracts these universities had for services from QS—the company that produces these rankings. The study compares the fluctuations in QS rankings with data obtained from the Times Higher Education rankings and data recorded by national statistics. The results suggest that the universities with frequent QS-related contracts had an increase of 0.75 standard deviations (~ 140 positions) in QS World University Rankings and an increase of 0.9 standard deviations in reported QS faculty-student ratio scores over 5 years, regardless of changes in the institutional characteristics. The observed distortions could be explained by university rankers’ self-serving bias that benefits both rankers and prestige-seeking universities and reinforces the persistence of rankings in higher education.
A shrimp between two worlds: the genetic differentiation of the brackish water shrimp Palaemon varians Leach, 1813 in the Baltic and the North Sea

Published: October 2022

AbstractThe patchy distribution of the ditch shrimp Palaemon varians (Palaemonidae) in small-scale habitats with low salinity may hint at isolation and fragmentation processes. In order to evaluate the extent to which gene flow barriers exist and salinity has an influence on this dispersal pattern, the genetic diversity and differentiation of Baltic and North Sea populations were investigated and set in context with sequence data from the Mediterranean Sea. Therefore, 133 sequences of a fragment of the cytochrome oxidase subunit 1 (COI) from 13 different populations from the Baltic Sea and North Sea were generated and complemented with publicly available sequences to estimate a haplotype network and calculate genetic differentiation and diversity. The results show that genetic differentiation correlates with geographic distance and the populations of the different basins are differentiated from each other. In contrast to the expectation, genetic differentiation was generally weak within basins. However, different clusters of differentiated populations could be revealed, indicating two migration events into the Baltic Sea.
Autistic People’s Perinatal Experiences I: A Survey of Pregnancy Experiences
Authors: Hampton Sarah , Allison Carrie , Baron-Cohen Simon , Holt Rosemary 
Published: October 2022

AbstractQualitative studies of autistic people’s pregnancy experiences have indicated sensory and communication related barriers to accessing adequate prenatal healthcare. However, quantitative work on the topic is scarce. This online survey study explored pregnancy experiences among 417 autistic and 524 non-autistic people. Compared with non-autistic people, autistic people reported heightened sensory and physical experiences during pregnancy and were more likely to experience prenatal depression and anxiety. Autistic people experienced lower satisfaction with prenatal healthcare, including having lower perceptions of their relationships with healthcare professionals and greater difficulties with antenatal classes. This study identifies key adjustments that can be made to prenatal healthcare, including sensory and communication adjustments. The findings highlight the need for greater autism understanding and awareness among professionals.
Negative Attributions as a Source of Vulnerability for trauma-related Shame and PTSD Symptoms
Authors: Seah Rebecca , Berle David 
Published: October 2022

AbstractShame is a common trauma response that is associated with the development and maintenance of PTSD. Phenomenological descriptions of shame indicate that shame arises from internal, stable and global causal attributions (negative attributions) for the precipitating event. The current study investigated whether negative attributions would be associated with higher levels of shame and PTSD, and whether shame would mediate the relationship between causal attributions and PTSD. As negative attributions may reflect a common transdiagnostic process in both depression and PTSD, it also examined whether depression would moderate this relationship. Eighty-seven participants meeting criteria for a Criterion A stressor were administered a structured PTSD diagnostic interview and a series of self-report measures. Findings indicate that shame mediated the relationship between internal, stable and global trauma-related causal attributions and PTSD symptoms. Further, depression did not moderate this relationship, indicating that negative causal attributions are associated with shame and PTSD independent of depression. Results provide empirical support for the cognitive concomitants of trauma-related shame, which raise the possibility that addressing negative attributions through cognitive therapeutic methods may be pertinent in reducing trauma-related shame. Future prospective data is needed to establish cognitive antecedents to shame.
Speeding-up one-versus-all training for extreme classification via mean-separating initialization
Authors: Schultheis Erik , Babbar Rohit 
Published: October 2022

AbstractIn this paper, we show that a simple, data dependent way of setting the initial vector can be used to substantially speed up the training of linear one-versus-all classifiers in extreme multi-label classification (XMC). We discuss the problem of choosing the initial weights from the perspective of three goals. We want to start in a region of weight space (a) with low loss value, (b) that is favourable for second-order optimization, and (c) where the conjugate-gradient (CG) calculations can be performed quickly. For margin losses, such an initialization is achieved by selecting the initial vector such that it separates the mean of all positive (relevant for a label) instances from the mean of all negatives – two quantities that can be calculated quickly for the highly imbalanced binary problems occurring in XMC. We demonstrate a training speedup of up to $$5\times$$

on Amazon-670K dataset with 670,000 labels. This comes in part from the reduced number of iterations that need to be performed due to starting closer to the solution, and in part from an implicit negative-mining effect that allows to ignore easy negatives in the CG step. Because of the convex nature of the optimization problem, the speedup is achieved without any degradation in classification accuracy.

HMGB1 induces radioresistance through PI3K/AKT/ATM pathway in esophageal squamous cell carcinoma
Authors: Zhang Xueyuan , Zou Naiyi , Deng Wenzhao , Song Chunyang , Yan Ke , Shen Wenbin , Zhu Shuchai 
Published: October 2022

Abstract
Background
To explore the effect of HMGB1 on the radio-sensitivity of esophageal cancer cells through regulating the PI3K/Akt/ATM pathway.

Methods and results
We observed the expression of HMGB1 and p-ATM in biopsies of esophageal cancer patients with immunohistochemical staining. Western blot and RT-qPCR were applied to detect the protein and RNA related to PI3K/Akt/ATM pathway, respectively. In addition, we inhibited the PI3K/Akt pathway with ly294002 and activated it with IGF1, then we explored the invasion, proliferation ability, and apoptosis of esophageal cancer cells in vitro by transwell, CCK8 assay, and flow cytometry respectively. In vivo, xenograft tumor model was established in nude mice to study the effect of HMGB1 on radioresistance via PI3K/AKT/ATM Signaling Pathway. The survival rate in patients with single positive/double negative expression of HMGB1 and p-ATM was significantly higher than in those with both positive expression of HMGB1 and p-ATM, the depletion of HMGB1 combined with ly294002 significantly inhibited cell proliferation and invasion ability, meanwhile, the addition of IGF1 reversed it. Meanwhile, depletion of HMGB1 and ly294002 promoted apoptosis and arrested the cancer cells in G0/G1 cell cycle with the decreased expression of Cyclin D1 and CDK4 and improved P16. We further validated these results in vivo, the application of HMGB1 silencing promoted apoptosis of xenograft tumors after radiation, especially combined with pathway inhibitor ly294002.

Conclusions
Esophageal cancer patients with high expression of HMGB1 and p-ATM have a poor prognosis after chemo-radiotherapy. Down-regulation of HMGB1 may promote the radio-sensitivity of esophageal cancer cells through regulating PI3K/Akt/ATM pathway.
Seizures in patients with IDH-mutated lower grade gliomas
Authors: Carstam Louise , Rydén Isabelle , Jakola Asgeir Store 
Published: October 2022

Abstract
Purpose
Most patients with Lower Grade Gliomas (LGG) present with epileptic seizures. Since the advent of molecular diagnostics, more homogenous sub-entities have emerged, including the isocitrate dehydrogenase-mutated (IDH-mutated) astrocytomas and 1p19q-codeleted oligodendrogliomas. We aimed to describe the occurrence of seizures in patients with molecularly defined LGG pre- and postoperatively and to analyze factors affecting seizure status postoperatively.

Methods
A population-based cohort of 130 adult patients with IDH-mutated WHO grade 2 or 3 astrocytomas and oligodendrogliomas was assessed pertaining to seizure burden before and after surgery.

Results
Fifty-four (79.4%) patients with astrocytoma and 45 (72.6%) patients with oligodendroglioma had a history of seizures before surgery. At 12 months postoperatively, 51/67 (76.1%) patients with astrocytoma and 47/62 (75.8%) patients with oligodendrogliomas were seizure free. In a multivariable logistic regression analysis, lower extent of resection (EOR) (OR 0.98; 95% CI 0.97–1.00, p = 0.01) and insular tumor location (OR 5.02; 95% CI 1.01–24.87, p = 0.048) were associated with presence of seizures within 1 year postoperatively in the entire LGG cohort. In sub-entities, EOR was in a similar manner associated with seizures postoperatively in astrocytomas (OR 0.98; 95% CI 0.96–0.99, p < 0.01) but not in oligodendrogliomas (p = 0.34).

Conclusion
Our results are well in line with data published for non-molecularly defined LGG with a large proportion of patients being seizure free at 1 year postoperative. Better seizure outcome was observed with increased EOR in astrocytomas, but this association was absent in oligodendrogliomas.
