Sex and Urban–Rural Differences in the Relationship between Childhood Sexual Abuse and Mental Health among Chinese College Students

This study aimed to reveal sex and urban–rural differences in the association between childhood sexual abuse (CSA) and mental health among Chinese college students. The study used data from the “National College Student Survey on Sexual and Reproductive Health 2019”, a cross-sectional study conducted in all 31 provinces of mainland China. Weighted logistic regression analysis was conducted to determine the association between CSA (noncontact CSA, contact CSA, and penetrative CSA) and mental health (suicide attempts and mental disorders). Among 49,728 students, 39.42% of the male participants and 43.55% of the female participants had ever experienced CSA. According to the OR results of logistic regression analysis, compared to females, males in the contact CSA group (AOR: 3.49, 95% CI: 1.95–6.23) and the penetrative CSA group (AOR: 8.79, 95% CI: 3.15–24.52) had higher odds of suicide attempts. Participants from rural and suburban areas that were categorized in the penetrative CSA group were more likely to report suicide attempts (rural: AOR: 4.01, 95% CI: 1.51–10.62, suburban AOR: 4.86, 95% CI: 2.52–9.36) and mental disorders (rural: AOR: 4.01, 95% CI: 1.51–10.62, suburban: AOR: 4.86, 95% CI: 2.52–9.36). In conclusion, the findings revealed a high prevalence of CSA in both sexes and reported that males are more vulnerable to the adverse effects of CSA. In addition, we also found that undergraduates growing up in rural and suburban areas are more vulnerable to the adverse psychological effects of CSA. Policymakers should pay more attention to this vulnerable population and implement effective measures to alleviate mental trauma.
Long-term scarring from institutional labelling: The risk of NEET of students from schools for learning disability in Germany

This article demonstrates the disadvantages that students leaving special needs schools (Förderschule) face in their school-to-work transition in Germany. We analyse whether the institutional label of ‘having attended a special needs school’ – beyond and above low school attainment – results in scarring effects for students’ chances of integration into training and employment after leaving school. We focus on students classified as having learning disability (Lernbehinderung), the largest group among students with special educational needs (SEN) and examine their NEET risk compared to equally low-attaining students from general schools at age 20/21. The analyses are based on rare longitudinal data for SEN students, the German National Educational Panel Study. Employing matching and regression techniques, we find that the label of ‘having attended a special needs school’ does generate long-term scars above and beyond low school attainment. However, this is only the case for school leavers with a lower secondary school certificate but not for those without school certificate.

Explore the Correlation between Environmental Factors and the Spatial Distribution of Property Crime

Comprehensively understanding the factors influencing crime is a prerequisite for preventing and combating crime. Although some studies have investigated the relationship between environmental factors and property crime, the interaction between factors was not fully considered in these studies, and the explanation of complex factors may be insufficient. This paper explored the influence of environmental factors on property crime using factor regression and factor interaction based on data from the central city of Lanzhou, China. Our findings showed that: (1) The distribution of crime cases showed the pattern of a local multi-center. Shop density, hotel density, entertainment density and house price were the four dominant environmental drivers of property crime; (2) The relationship between the light intensity and property crime had different correlation explanations in temporal projection and spatial projection. There was a normal distribution curve between the number of property crimes and the Price-to-Earnings Ratio (PE Ratio) of the community house price; and (3) The results of the factor interaction indicated that the effect of all factors on crime showed a two-factor enhancement. As an important catalyst, shop density had the strongest interaction with other factors. Shop density gradient influenced the degree of interpretation of spatial heterogeneity of property crime.
Backstresses in geologic materials quantified by nanoindentation load-drop experiments

ABSTRACT Transient creep of geologic materials is inferred to control many large-scale phenomena such as post-seismic deformation and post-glacial isostatic readjustment. Viscoelastic simulations can reproduce transient creep measured at Earth’s surface via GPS, but these approaches are entirely phenomenological, lacking a microphysical basis. This empirical nature limits our ability to extrapolate to future events and longer time scales. Recent experimental work has identified the importance of strain hardening and backstresses among dislocations in the transient deformation of geologic materials at both high and low temperatures, but very few experimental measurements of such backstresses exist. Here, we develop a nanoindentation load-drop method that can measure the magnitude of backstresses in a material. Using this method and a self-similar Berkovich tip, we measure backstresses in single crystals of olivine, quartz, and plagioclase feldspar at a range of indentation depths from 100–1750 nm, corresponding to geometrically necessary dislocation (GND) densities of order 1014–1015 m−2. Our results reveal a power-law relationship between backstress and GND density with an exponent ranging from 0.44–0.55 for each material, in close agreement with the theoretical prediction (0.5) from Taylor hardening. This work supports the assertion that backstresses and their evolution must be considered in future models of both transient and steady-state deformation in the Earth. GRAPHICAL ABSTRACT
Low-Intensity Pulsed Ultrasound Enhanced Adipose-Derived Stem Cell-Mediated Angiogenesis in the Treatment of Diabetic Erectile Dysfunction through the Piezo-ERK-VEGF Axis

Objectives Erectile dysfunction is a major comorbidity of diabetes. Stem cell transplantation is a promising method to treat diabetic erectile dysfunction. In this study, we evaluated whether low-intensity pulsed ultrasound (LIPUS) could enhance the efficacy of adipose-derived stem cells (ADSCs) and investigated the underlying molecular mechanism. Materials and methods. Sixty 8-week-old male Sprague–Dawley rats were randomly divided into the normal control (NC) cohort or the streptozocin-induced diabetic ED cohort, which was further subdivided into DM, ADSC, LIPUS, and ADSC+LIPUS groups. Rats in the ADSC or ADSC+LIPUS group received ADSC intracavernosal injection. Rats in the LIPUS or ADSC+LIPUS group were treated with LIPUS. The intracavernous pressure (ICP) and mean arterial pressure (MAP) were recorded at Day 28 after injection. The corpus cavernosum tissues were harvested and subjected to histologic analysis and ELISA. The effects of LIPUS on proliferation and cytokine secretion capacity of ADSCs were assessed in vitro. RNA sequencing and bioinformatic analysis were applied to predict the mechanism involved, and western blotting and ELISA were used for verification. Results Rats in the ADSC+LIPUS group achieved significantly higher ICP and ICP/MAP ratios than those in the DM, ADSC, and LIPUS groups. In addition, the amount of cavernous endothelium and cGMP level also increased significantly in the ADSC+LIPUS group. In vitro experiments demonstrated that LIPUS promoted proliferation and cell cycle progression in ADSCs. The excretion of cytokines such as CXCL12, FGF2, and VEGF was also enhanced by LIPUS. Bioinformatic analysis based on RNA sequencing indicated that LIPUS stimulation might activate the MAPK pathway. We confirmed that LIPUS enhanced ADSC VEGF secretion through the Piezo-ERK pathway. Conclusion LIPUS enhanced the curative effects of ADSCs on diabetic erectile dysfunction through the activation of the Piezo-ERK-VEGF pathway. ADSC transplantation combined with LIPUS could be applied as a synergistic treatment for diabetic ED.
Persistence of Anti-SARS-CoV-2 Spike IgG Antibodies Following COVID-19 Vaccines

Purpose This study was conducted to investigate antibody immune responses induced by BNT162b2 and AZD1222 human COVID-19 vaccines in Riyadh city, Saudi Arabia. Patients and Methods ELISA was used to evaluate antibodies, against the SARS-CoV-2 spike S1 protein, in serum samples from 432 vaccinated individuals at six time points: pre-vaccination (baseline), post-prime, post-boost, 6-months, and 1 year post-vaccination, and 3 weeks post a third dose. Virus microneutralization assay was used to confirm antibody responses in a subset of samples. Results Anti-SARS-CoV-2 spike IgG were detected in most subjects post-prime, reached a peak level post-boost, and remained at high level at the 6-month follow-up. At 1 year post-vaccine, the antibody levels were low but increased to a significant level higher than the peak following a third dose. The third dose was given at an average of 250 days after the second dose. The virus microneutralization assay confirmed the neutralization activity of the induced SARS-CoV-2 IgG antibodies. The vaccines induced higher IgG titres at post-prime (p=0.0001) and 6 months (p=0.006) in previously infected individuals. An increased interval between prime and boost, more than recommended time, appeared to enhance the IgG levels (p=0004). Moreover, the vaccines induced higher IgG levels in younger subjects (p=0.01). Conclusion These data provide insights and build on the current understanding of immune responses induced by these two vaccines; and support a third boosting dose for these COVID-19 vaccines.
Women Entrepreneurs in Saudi Arabia: A Portrait of Progress in the Context of their Drivers and Inhibitors

This study explores the barriers and challenges faced by Saudi women entrepreneurs along with the motivational forces that drives them towards entrepreneurship. This study employs a qualitative research design, and is based on the interview of 11 Saudi women entrepreneurs and includes a review of data on the motivational factors and challenges faced by them using interpretative phenomenological analysis. Research participants’ perspectives have been quoted for each distinct theme that emerged from the interview finding. The factors motivating Saudi women towards entrepreneurship have been identified as passion, identification of opportunity, dissatisfaction and family support. Barriers that are exclusive to Saudi women entrepreneurs are difficulty in maintaining work-life balance, lack of business networking, limited access to financial resources, lack of understanding of business-related tasks and functions, fear of deception, lack of trust, reservation about work-related travel, recruitment and training issues like lack of experienced and trained Saudi workers and negative attitude and non-willingness to work under female leadership. Decision-makers in government and other relevant organisations can develop a solid framework of focussed agendas, policies and measures to address the barriers identified in this study. Arab countries especially Saudi Arabia can use these results to fully utilise the entrepreneurial skills of Saudi women to boost economic growth and development. This pioneering study reveals the intricacy of Saudi women entrepreneurs’ experiences in the presence of gender-bias and internalising socio-cultural values and attributed gender roles during the formation of their entrepreneurial identities through a unique non-western viewpoint.
Applicability of an international linear appraisal system in Murciano-Granadina breed: fitting, zoometry correspondence inconsistencies, and improving strategies

Abstract Linear appraisal systems (LAS) are effective strategies to systematically collect zoometric information from animal populations. Traditionally applied LAS in goats was developed considering the variability and scales found in highly selected breeds. As a result, traditional LAS may no longer cover the different contexts of goat breeds widespread throughout the world, and departures from normality may be indicative of the different stages of selection at which a certain population can be found. The present study aimed to evaluate the distribution and symmetry properties of twenty-eight zoometric traits. After symmetry analysis was performed, the scale readjustment proposal suggested specific strategies should be implemented such as scale reduction of lower or upper levels, determination of a setup moment to evaluate and collect information from young (up to 2 years) and adult bucks (over 2 years), the addition of upper categories in males due to upper values in the scale being incorrectly clustered together. The particular analysis of each variable permits determining specific strategies for each trait and serve as a model for other breeds, either selected or in terms of selection. Highlights Specific strategies must be approached for each particular zoometric trait. Scale levels for limb related traits must be readjusted. An extension of the scale in the stature of males is proposed. Males must be subdivided into two categories (below and over two years). Environment adaptability shapes progress for better dairy-linked zoometry.
Retirement Planning Through Financial Literacy/Knowledge: A Bibliometric Analysis Perspective

Personal retirement planning is not a mandatory exercise; it is a voluntary preparation for the future. Regrettably, many are unprepared for this. Most people believe retirement planning is necessary just when they are approaching retirement or are too young to consider their retirement years. As such, retirement isn't only about relaxing in the "golden years. " Instead, people must plan and invest for retirement to be financially secure during those years. This study will use bibliometric analysis to overview the published scientific literature on retirement planning. The Scopus database compiled all available retirement planning literature. The keyword search yielded 108 documents that were filtered out. In peer-reviewed journals or conference proceedings, all publications were authored in English. Most of these papers were in the subjects of Economics, Econometrics and Finance, Business, Management, Accounting, and Social Sciences. The bibliometric study summarises the literature on retirement planning and identifies future research opportunities.
Infrared properties of La2-x(Ca,Sr)(x)CaCu2O6+delta single crystals

The in-plane optical properties of two crystals of the bilayer cuprate La2-x(Ca,Sr)(x)CaCu2O6+delta, one with excess Ca and x=0.10 and the other with Sr and x=0.15, were investigated over the frequency range of 45-25 000 cm(-1). The optical conductivity has been derived from Kramers-Kronig transformation. Each crystal exhibits a peak at around 15 000 cm(-1), which corresponds to the charge-transfer (CT) excitation of the parent insulator. With increasing carrier density, spectral weight shifts from the CT excitation to the low-omega region. For the superconducting sample (x=0.15), the optical conductivity displays a peak in the far-infrared region, which shifts toward zero frequency with decreasing temperature. The temperature-dependent behavior favors a dynamical localization picture. A "pseudogap" feature is observed in the low-frequency reflectance and the scattering rate spectra. Both the energy scale and the temperature dependence of the pseudogap are similar to other bilayer cuprates.
Neighborhood Disorder and Health-Related Work Absences: Perceived Control and Neighborhood Trust as Explanatory Mechanisms

The current research argues that people residing in disordered neighborhoods will tend not to trust their neighbors and perceive less control over life, which will in turn increase the risk of health-related work absences. Researchers also suggest that lower trust in neighbors and perceived control will strengthen the association between living in disordered neighborhoods and risk of health-related work absences. To address these questions, we examine a national study of Canadian workers gathered at the individual level in September of 2019 (N=2,524). Multinomial regression models show that perceptions of neighborhoods as disordered are associated with a greater likelihood of frequent health-related work absences. Reduced trust in neighbors and perceived control largely explain this association, but these factor do not moderate the association. This research contributes to the study of neighborhoods and health by showing that adverse health effects of disordered neighborhoods can have subsequent socioeconomic implications through increased health-related work absences.
The Lyα Forest from Gravitational Collapse in the Cold Dark Matter + Λ Model

We use an Eulerian hydrodynamic cosmological simulation to model the Lyα forest in a spatially flat, COBE-normalized, cold dark matter model with) Ω = 0.4. We find that the intergalactic, photoionized gas is predicted to collapse into sheetlike and filamentary structures which give rise to absorption lines having characteristics similar to the observed Lyα forest. A typical filament is ~500 h–1 kpc long with thickness ~50 h–1 kpc (in proper units), and baryonic mass ~ 1010 h−1 M☉. In comparison our cell size is (2.5, 9) h−1 kpc in the two simulations we perform, with true resolution perhaps a factor of 2.5 worse than this. The gas temperature is in the range 104-105 K, and it increases with time as structures with larger velocities collapse gravitationally. We show that the predicted distributions of column densities, b-parameters, and equivalent widths of the Lyα forest clouds agree reasonably with observations, and that their evolution is consistent with the observed evolution, if the ionizing background has an approximately constant intensity between z = 2 and z = 4. A new method of identifying lines as contiguous regions in the spectrum below a fixed flux threshold is suggested to analyze the absorption lines, given that the Lyα spectra arise from a continuous density field of neutral hydrogen rather than discrete clouds. We also predict the distribution of transmitted flux and its correlation along a spectrum and on parallel spectra, and the He ii flux decrement as a function of redshift. We predict a correlation length of ~80 h−1 kpc perpendicular to the line of sight for features in the Lyα forest. In order to reproduce the observed number of lines and average flux transmission, the baryon content of the clouds may need to be significantly higher than in previous models because of the low densities and large volume-filling factors we predict. If the background intensity JH I is at least that predicted from the observed quasars, Ωb needs to be as high as ~0.25 h−2. The model also predicts that most of the baryons at z > 2 are in Lyα clouds, and that the rate at which the baryons move to more overdense regions is slow. A large fraction of the baryons which are not observed at present in galaxies might be intergalactic gas in the currently collapsing structures, with T ~ 105–106 K. All our results on the statistical properties of the simulated spectra are predictions that can be directly tested by applying the same methods to observed spectra. We are making the simulated spectra electronically available.
Variability and Predictability of the Bering Strait Ocean Heat Transport and Arctic Ocean Sea Ice Extent

Background: This study examines the monthly, seasonal, and interannual variations in Pacific Ocean heat transport entering the Arctic Ocean through the Bering Strait, and its influence on sea ice extent in the Arctic Ocean. Methods: Monthly ocean heat transport is calculated using temperature and volumetric transport data from moorings deployed in the Bering Strait. Pearson correlations are calculated between the observed detrended monthly cumulative Bering Strait ocean heat transport and the detrended monthly sea ice extent time series from May through September. Results: An increase in the spring variability of the Bering Strait ocean heat transport is found since 2010, associated with both increased volume flux and water temperatures in May and June. A significant negative correlation between the Bering Strait ocean heat transport and Arctic sea ice extent in the Pacific sector is observed for May, June, and July, both within and outside the marginal ice zone, with a sharp decline in predictability for August and September. Conclusion: The Bering Strait ocean heat transport is a skillful predictor for early melt season sea ice extent in the Pacific sector but loses predictive skills later in the summer in August and September due to changes in ice dynamics, in accordance with the loss of predictive skill in Global Climate Models.
Functional Connectivity within the Frontal–Striatal Network Differentiates Checkers from Washers of Obsessive-Compulsive Disorder

Background: Obsessive-compulsive disorder (OCD) is a psychiatric disorder with high clinical heterogeneity manifested by the presence of obsessions and/or compulsions. The classification of the symptom dimensional subtypes is helpful for further exploration of the pathophysiological mechanisms underlying the clinical heterogeneity of OCD. Washing and checking symptoms are the two major symptom subtypes in OCD, but the neural mechanisms of the different types of symptoms are not yet clearly understood. The purpose of this study was to compare regional and network functional alterations between washing and checking OCD based on resting-state functional magnetic resonance imaging (rs-fMRI). Methods: In total, 90 subjects were included, including 15 patients in the washing group, 30 patients in the checking group, and 45 healthy controls (HCs). Regional homogeneity (ReHo) was used to compare the differences in regional spontaneous neural activity among the three groups, and local indicators were analyzed by receiver operating characteristic (ROC) curves as imaging markers for the prediction of the clinical subtypes of OCD. Furthermore, differently activated local brain areas, as regions of interest (ROIs), were used to explore differences in altered brain functioning between washing and checking OCD symptoms based on a functional connectivity (FC) analysis. Results: Extensive abnormalities in spontaneous brain activity involving frontal, temporal, and occipital regions were observed in the patients compared to the HCs. The differences in local brain functioning between checking and washing OCD were mainly concentrated in the bilateral middle frontal gyrus, right supramarginal gyrus, right angular gyrus, and right inferior occipital gyrus. The ROC curve analysis revealed that the hyperactivation right middle frontal gyrus had a better discriminatory value for checking and washing OCD. Furthermore, the seed-based FC analysis revealed higher FC between the left medial superior frontal gyrus and right caudate nucleus compared to that in the healthy controls. Conclusions: These findings suggest that extensive local differences exist in intrinsic spontaneous activity among the checking group, washing group, and HCs. The neural basis of checking OCD may be related to dysfunction in the frontal–striatal network, which distinguishes OCD from washing OCD.
