Criminal Policy Preferences Among the Public and the Police: A Comparison

Through surveys in Flanders (Belgium), the article investigates the criminal policy preferences of the public and the police, a topic of considerable policy relevance that has so far received limited academic attention. It describes and compares such preferences both for specific crimes, within the realm of the criminal justice (CJ) process, and in general, considering interventions that reflect the broadening scope of contemporary criminal policy. Data from 2,348 citizens and 381 police officers point to the capability of both groups to discriminate, that is, to support different CJ interventions depending on the crimes considered, and shows that, for most crimes, the public backs more lenient interventions than the police. Instead, both groups’ general criminal policy preferences are quite similar.

How to Assess Livelihoods? Critical Reflections on the Use of Common Indicators to Capture Socioeconomic Outcomes for Ecological Restoration workers in South Africa

Social outcomes from conservation and development activities on a local scale are often assessed using five livelihood assets—Natural, Physical, Human, Financial and Social—and their associated indicators. These indicators, and the variables used to measure them, are typically based on ‘common practice’ with limited attention being paid to the use of alternative indicators. In this article, we present a typical survey of socioeconomic benefits for ecological restoration workers in South Africa, and ask whether the common livelihood indicators used are adequate and sufficient, or whether any relevant indicators are missing. Results from the livelihood survey show the value of income, food and education as strong indicators of financial and human assets, and the importance of open-ended questions in eliciting details of workers’ perceived changes in their livelihoods. However, by complementing the survey results with qualitative data from semi-structured interviews and stakeholder workshops, we show how unconventional livelihood indicators and aspects provide a deeper understanding of changes in livelihoods that are tied to restoration projects. We guide scholars and practitioners to advance their process of selecting livelihood indicators, in particular to include three additional types of indicators: intangible indicators to assess life quality; relative indicators reaching across spatial and temporal scales to capture community outcomes and livelihood resilience; and, political indicators to uncover causal relationships.

Guardians Looking From Outside: Gendered Experiences of Labor Migration and Psychosocial Health Among Nepalese Migrant Fathers and Left-Behind Mothers.

Nepalese migrant workers are at heightened risk of adverse mental health problems. However, the social mechanisms by which experiences of labor migration create such vulnerabilities are not well understood. Moreover, limited attention has been paid to the experiences of left-behind spouses. This study explores how migrant fathers and left-behind mothers experience labor migration and how migration affects mental health across migrant household members, paying special attention to the role of gender. We conducted 29 in-depth interviews with Nepalese migrant fathers (N = 18) in South Korea and left-behind mothers (N = 11) in Nepal. Labor migration imposes substantial stress on the entire family. Migrant fathers discussed their feelings of guilt and worry regarding their relationships with their children due to physical and emotional distance. Left-behind mothers indicated loneliness and caregiver stress due to additional responsibilities as a single parent. Migrant fathers reported that they felt respected by their communities for their work, while left-behind mothers felt heavily scrutinized. Our findings highlight how labor migration reinforces gender inequalities in domestic responsibilities and norms regarding the expected roles of migrating men and left-behind women. These findings suggest that psychosocial services must be tailored to the unique needs of migrant workers and left-behind families.

Low-tortuosity, high-loading electrodes for fast-charging quasi-solid-state lithium metal batteries

Structural design of electrodes is a widely adopted approach towards enhanced electrochemical performance in various battery systems. However, in quasi-solid-state lithium metal batteries, research has predominantly focused on developing gel polymer electrolytes (GPEs), with limited attention given to utilizing electrodes with specialized structural design. Herein, by exploiting the excellent wettability and permeability of the GPE, high-loading NMC-811 cathodes featuring aligned channels achieved through freeze-casting are integrated with in-situ UV-polymerized poly (butyl acrylate) (PBA). The aligned channels in the freeze-cast electrodes provide low-tortuosity pathways for smooth Li+ transport, facilitating rapid kinetics. Consequently, superior areal capacity can be delivered under high areal current density (e.g. 1 mAh cm−2 at 2 mA cm−2 and 0.7 mAh cm−2 at 3.8 mA cm−2), demonstrating the fast-charging capability of quasi-solid-state lithium metal batteries.

Gaussian modeling with B-splines for spatial functional data on irregular domains

Functional Data Analysis (FDA) has emerged as a powerful framework for datasets that exhibit continuous variation over specified intervals. Unlike traditional methods, FDA treats data as functions, providing a more comprehensive understanding of their behavior and variability. This approach is particularly beneficial for exploring observations collected over time or space. The Spatial Functional Data Analysis (SFDA) incorporates spatial locations as an additional dimension. This integration enhances the ability to model complex associations between curves in the functional domain. Despite progress in analyzing multivariate spatial data, limited attention has been given to SFDA. This study addresses this gap by proposing a Bayesian Gaussian functional approach based on B-splines. The proposal also addresses challenges posed by irregularly spaced observations in the functional domain, a feature rarely considered in the literature. A simulation study is developed to evaluate performance. Finally, results are explored using a relatively novel real dataset from monitoring stations of temperature in Mexico City.

Experiences of service and diagnosis among immigrant families of young children with suspected or diagnosed developmental disabilities

ABSTRACT Objectives While early diagnosis is fundamental to the development of children with developmental disabilities (DD), limited attention has been paid to immigrant parents’ experience of early encounters with systems when they begin seeking supports for their children with DD. This study aimed to contribute to better understanding of immigrant parents’ experiences of early encounters with services for families and children with suspected or diagnosed DD. Design A longitudinal, qualitative approach was adopted. Over 12 months, multiple interviews were conducted with four immigrant families with children aged between two and four years who were attending a mobile playgroup offering early learning supports for children with suspected or diagnosed DD in communities with low access to formal supports. During the first three months of the study, families were accompanied by the first author on weekly visits to the playgroup. Participant observations and informal discussions with staff delivering early intervention supports via the playgroup provided further insight into families’ initial and on-going encounters with services and supports. During the remaining nine months, multiple interviews were conducted with participating families, to document their on-going experiences and encounters with medical practitioners and therapists. Results Thematic analysis of data generated four key themes: Initial encounters with medical professionals, Confusion and ‘missed’ diagnosis, Gaps in understanding, collaboration and communication, and Families’ desire to learn and implement strategies. Conclusion Families made concerted efforts to locate appropriate supports. They also faced barriers including a lack of openness and genuine consultation, particularly in their encounters with health professionals. These barriers resulted in a level of mistrust and detachment from formalised supports. Results highlight the critical importance for health professionals of ‘tuning into’ family concerns through relationship-based approaches, in order to establish shared understanding and mutual respect between professionals and families, particularly for immigrant families seeking support for their young children.

Tick extracellular vesicles undermine epidermal wound healing during hematophagy.

Wound healing has been extensively studied through the lens of inflammatory disorders and cancer, but limited attention has been given to hematophagy and arthropod-borne diseases. Hematophagous ectoparasites, including ticks, subvert the wound healing response to maintain prolonged attachment and facilitate blood-feeding. Here, we unveil a strategy by which extracellular vesicles (EVs) ensure blood-feeding and arthropod survival in three medically relevant tick species. We demonstrate through single cell RNA sequencing and murine genetics that wildtype animals infested with EV-deficient Ixodes scapularis display a unique population of keratinocytes with an overrepresentation of pathways connected to wound healing. Tick feeding affected keratinocyte proliferation in a density-dependent manner, which relied on EVs and dendritic epidermal T cells (DETCs). This occurrence was linked to phosphoinositide 3-kinase activity, keratinocyte growth factor (KGF) and transforming growth factor β (TGF-β) levels. Collectively, we uncovered a strategy employed by a blood-feeding arthropod that impairs the integrity of the epithelial barrier, contributing to ectoparasite fitness.

A severe head louse (Pediculus humanus capitis) infestation: Timeline, pathogen detection, kdr-gene screening and morphological anomalies of lice.

Lice are assuming an increasing importance in forensic investigations, given their capacity to provide information about an individual's care. Head louse pediculosis is a frequent condition in school-age children and can be properly controlled using topical treatments combined with good personal hygiene. Prolonged and chronic infestations may result in more serious outcomes including severe iron deficiency anaemia. We conducted entomological and laboratory investigations of a head louse infestation in a 12-year-old girl who experienced severe anaemia and subsequent death. Numerous lice were found postmortem on the head, face and neck of the patient, as well as on bedding and clothing. Analysis of nits on individual hairs determined that the louse infestation had been present for at least 166 days. The lice had some morphological traits characteristic of body lice: the third antennal segment in some specimens was distinctly longer than wide, and the apices of some paratergal plates did not extend into intersegmental membranes, while other morphological features were characteristic of head or body lice. All lice were heterozygous for the T917I kdr genotype, a marker of permethrin resistance. Nineteen (79.2%, 95%CI 59.5%-90.8%) louse DNA samples tested TaqMan positive for Acinetobacter (Moraxellales; Moraxellaceae) sp. Available information and laboratory findings are further discussed regarding their possible contribution to the negative outcome of this case. We stress the impact head louse pediculosis can have on children with limited parental attention, and how severe head louse infestation may serve as warning sign of neglect, and other high-risk situations.

Lymphocyte to high density lipoprotein ratio can predict the short-term prognosis of hepatitis B virus-related acute-on-chronic liver failure patients

BackgroundAcute-on-chronic liver failure (ACLF) is a syndrome characterized by systemic inflammation, leading to high short-term mortality. The lymphocyte to high-density lipoprotein ratio (LHR) has been introduced as a novel marker of inflammation. However, its role as a prognostic inflammatory biomarker in the context of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) has received limited attention. MethodsWe retrospectively included 272 patients with HBV-ACLF who met the definition of APALC. Data on clinical features and laboratory tests were collected from medical records within 24 h. Logistic regression was used to identify risk factors for poor short-term prognosis, and LHR-based prediction (LHRB) models were constructed based on risk factors. Furthermore, the accuracy of the LHRB model was validated through rigorous testing. ResultsIn the survival and death groups, there were statistical differences in their CTP, MELD, MELD-Na, COSSH-ACLF II scores, and LHR. Multivariate logistic regression identified seven predictors significantly associated with 28-day mortality. Furthermore, statistically significant differences in short-term mortality and certain clinical laboratory tests for poor prognosis were observed between the high and low LHR groups. To assess the predictive performance of various models in terms of short-term mortality, the area under the receiver operating characteristic curve (AUROC) was calculated. The AUROC values for the CTP, MELD, MELD-Na, COSSH-ACLF II, and LHRB models were found to be 0.725, 0.788, 0.772, 0.871, and 0.877, respectively. The results in the validation group were similar to those in the training group, and the validation results suggested excellent performance of the LHRB model. ConclusionLHR levels have the potential to serve as indicators for the prognosis of HBV-ACLF. Additionally, the recently developed LHRB model offers an accessible risk assessment tool.

Association between non-injection drug use and hepatitis C infection among HIV-negative men who have sex with men

BackgroundPrior research predominantly examined the association between HIV-positive men who have sex with men (MSM) or those using injection drugs and hepatitis C virus (HCV) infection. However, limited attention has been given to understanding the association among HIV-negative MSM who do not inject drugs. This gap leaves apportion of the population unexamined, potentially overlooking important factor that may contribute to the transmission and prevalence of HCV. This study aims to investigate the relationship between non-injection drug use and HCV infection in this population.MethodsIn this cross-sectional study, we analyzed data on 118 MSM who reported use of non-injection drugs. The participants were recruited from two inner-city communities in Houston, TX, between 2004 and 2007 and were negative for both HIV and hepatitis B virus infection. Latent class analysis (LCA) was used to identify drug use latent classes. Multinomial logistic regression analysis was used to evaluate the association between drug use latent class and HCV infection.ResultsFour distinct latent classes of drug use were identified: class 1, persons ≥ 42 years of age who used only crack cocaine; class 2, persons approximately 42 years of age who used > 2 drugs; class 3, persons < 42 years of age who used > 5 drugs; and class 4, persons ≥ 42 years of age who used > 6 drugs. Class 4 was significantly associated with HCV infection. The odds of HCV infection in members of class 4 was 17 times higher than in class 2 members (adjusted odds ratio [aOR] = 16.9, 95% confidence interval [CI]: 1.4–205.4) and almost 22 times higher than in class 3 members (aOR = 21.8, 95% CI: 1.5–322.8).ConclusionsAmong MSM with non-injection drug use, the subgroup of individuals who were ≥ 42 years of age and used multiple drugs (including heroin, speedball, methamphetamine, crack cocaine, and marijuana) had a high probability of HCV infection. Public health and education programs, as well as drug treatment and rehabilitation programs, should be developed for this high-risk subgroup of individuals to prevent HCV acquisition and transmission.

Reductive Elimination from Tetra-Alkyl Cuprates [Me n Cu(CF3)4- n ]- (n = 1 - 4): Beyond Simple Oxidation States.

In recent years, the electronic structures of organocuprates in general and the complex [Cu(CF3)4]- in particular have attracted significant interest. A possible key indicator in this context is the reactivity of these species. Nonetheless, this aspect has received only limited attention. Here, we systematically study the series of tetra-alkyl cuprates [MenCu(CF3)4-n]- and their unimolecular reactivity in the gas phase, which includes concerted formal reductive eliminations as well as radical losses. Through computational studies, we characterize the electronic structures of the complexes and show how these are connected to their reactivity. We find that all [MenCu(CF3)4-n]- ions feature inverted ligand fields and that the distinct reactivity patterns of the individual complexes arise from the interplay of different effects.

DEVELOPMENT OF A CORRELATION MODEL FOR TORSIONAL SHEAR MODULUS PROPERTIES BETWEEN STRUCTURAL SIZE SPECIMENS BASED ON EN 384:2016 AND SMALL CLEAR SPECIMENS (MS544: PART 2)

In timber design, the shear modulus of beams is crucial for ensuring torsional stability and minimizing vibrational issues. Traditionally, the ratio of modulus of elasticity (E) to shear modulus (G) is assumed to be 16:1. However, bending tests often combine flexural and shear stresses, making it difficult to assess pure shear properties. The British Standard BS EN 408:2012 now recommends the torsion test as the preferred method for determining the shear modulus of structural-size timber and timber composites. This method has received limited attention in Malaysia. This study investigates the torsional shear modulus of Malaysian tropical timber species across different strength groups (SG), including Balau (SG1), Kempas (SG2), Kelat (SG3), Kapur (SG4), Resak (SG4), Keruing (SG5), Mengkulang (SG5), Light Red Meranti (SG6), and Geronggang (SG7). Torsion tests were conducted in line with BS EN 408, and the results were compared with modulus of elasticity values from MS554: Part 2. The findings showed that the E to G ratio for these species ranged from 17:1 to 29:1, with an average of 21:1—exceeding the conventional 16:1 ratio. This indicates that torsional shear modulus must be experimentally tested rather than inferred from the traditional ratio.

APP-CD74 axis mediates endothelial cell-macrophage communication to promote kidney injury and fibrosis.

Kidney injuries often carry a grim prognosis, marked by fibrosis development, renal function loss, and macrophage involvement. Despite extensive research on macrophage polarization and its effects on other cells, like fibroblasts, limited attention has been paid to the influence of non-immune cells on macrophages. This study aims to address this gap by shedding light on the intricate dynamics and diversity of macrophages during renal injury and repair. During the initial research phase, the complexity of intercellular communication in the context of kidney injury was revealed using a publicly available single-cell RNA sequencing library of the unilateral ureteral obstruction (UUO) model. Subsequently, we confirmed our findings using an independent dataset from a renal ischemia-reperfusion injury (IRI) model. We treated two different types of endothelial cells with TGF-β and co-cultured their supernatants with macrophages, establishing an endothelial cell and macrophage co-culture system. We also established a UUO and an IRI mouse model. Western blot analysis, flow cytometry, immunohistochemistry and immunofluorescence staining were used to validate our results at multiple levels. Our analysis revealed significant changes in the heterogeneity of macrophage subsets during both injury processes. Amyloid β precursor protein (APP)-CD74 axis mediated endothelial-macrophage intercellular communication plays a dominant role. In the in vitro co-culture system, TGF-β triggers endothelial APP expression, which subsequently enhances CD74 expression in macrophages. Flow cytometry corroborated these findings. Additionally, APP and CD74 expression were significantly increased in the UUO and IRI mouse models. Immunofluorescence techniques demonstrated the co-localization of F4/80 and CD74 in vivo. Our study unravels a compelling molecular mechanism, elucidating how endothelium-mediated regulation shapes macrophage function during renal repair. The identified APP-CD74 signaling axis emerges as a promising target for optimizing renal recovery post-injury and preventing the progression of chronic kidney disease.

Exploring Latino cultural factors from the perspective of sexual minority men in the USA

Existing research on Latino cultural factors mainly focuses on gender and nationality, often overlooking sexual orientation and giving limited attention to the experiences of Latino sexual minority men in the United States of America (USA). This study addressed this gap by exploring how sexual minority men identify, describe and experience Latino cultural factors. Between April and December 2019, semi-structured interviews were conducted with 28 men (ages 18–40, 43% non-US-born) in the greater Miami, Florida area to explore their engagement in HIV prevention and behavioural health services. Secondary qualitative analysis examined five Latino cultural factors (personalismo, machismo, familismo, fatalismo and curanderismo), informed by the existing literature for initial coding and supplemented by the use of an inductive approach, yielding 14 subthemes. Findings revealed that although participants often described cultural factors in their traditional interpretations within the Latino community at large, they also highlighted unique experiences, particularly for relationship-oriented factors like personalismo, machismo and familismo. Sexual orientation stigma shaped participants’ experiences of these cultural factors. Study findings enhance knowledge about Latino sexual minority men’s lived experiences in the USA, underscoring how cultural factors are perceived both traditionally and uniquely, and emphasises the need for nuanced, culturally tailored assessments in future research.

A Graded Redox Interfacial Modifier for High-Performance Perovskite Solar Cells.

Perovskite solar cells have emerged as a potential competitor to the silicon photovoltaic technology. The most representative perovskite cells employ SnO2 and spiro-OMeTAD as the charge-transport materials. Despite their high efficiencies, perovskite cells with such a configuration show unsatisfactory lifespan, normally attributed to the instability of perovskites and spiro-OMeTAD. Limited attention was paid to the influence of SnO2, an inorganic material, on device stability. Here we show that improving SnO2 with a redox interfacial modifier, cobalt hexammine sulfamate, simultaneously enhances the power-conversion efficiency (PCE) and stability of the perovskite solar cells. Redox reactions between the bivalent cobalt complexes and oxygen lead to the formation of a graded distribution of trivalent and bivalent cobalt complexes across the surface and bulk regions of the SnO2. The trivalent cobalt complex at the top surface of SnO2 raises the concentration of (SO3NH2)- which passivates uncoordinated Pb2+ and relieves tensile stress, facilitating the formation of perovskite with improved crystallinity. Our approach enables perovskite cells with PCEs of up to 24.91%. The devices retained 93.8% of their initial PCEs after 1000 hours of continuous operation under maximum power point tracking. These findings showcase the potential of cobalt complexes as redox interfacial modifiers for high-performance perovskite photovoltaics.

Developing a suitability assessment model for Public Private Partnerships: a case in urban China

Spatial heterogeneity is a fundamental aspect of Public Private Partnerships (PPPs). The appropriateness of PPPs applications varies across regions. While the assessment of suitability for PPPs is crucial, it has received limited scholarly attention. This study, using China as s representative case, developed a suitability assessment model and evaluated it across 287 prefecture-level cities in China. The results reveal considerable spatial variation in the suitability of PPPs within the country. Utilizing the natural breakpoint method, this study categorized Chinese cities into four distinct levels of PPP suitability: high, medium, low, and unsuitable. 219 cities were identified as either unsuitable or having low suitability for PPPs, suggesting that PPPs may not be broadly applicable in the current Chinese context. This study not only lays the groundwork for sustainable PPP application in China but also significantly contributes to shaping strategies for successful PPP implementation globally.

Dyschromatopsia due to welding arcs: An underestimated occupational injury

Welders are at risk of developing dyschromatopsia, a color vision deficiency, due to occupational exposure, including welding arcs. This visual impairment can impact occupational safety and performance but has received limited attention in research. : This study aimed to investigate the prevalence and characteristics of defective color vision among welders exposed to welding arcs. A cross-sectional study was conducted with 52 male welders working in various industries. Demographic and occupational data were collected through a questionnaire. Color vision assessment was performed using Ishihara and Farnsworth Munsell test. Welding exposure data were collected through self-reporting and workplace observations. Chi-square test was used for data analysis. A p-value of less than 0.05 was considered statistically significant. The prevalence of defective color vision among welders was 15.4%. Age, gender, years of experience, and types of welding performed did not significantly influence the prevalence. Welders in the age group of 31-40 years showed a higher prevalence. Inadequate use of eye protection was identified as a barrier to preventing color vision impairments. Defective color vision is a prevalent occupational injury among welders exposed to welding arcs. The study underscores the importance of preventive measures, including proper eye protection and education programs, to reduce the risk of visual impairments and improve occupational safety. Further research is needed to understand the long-term consequences of welding arc exposure on color vision and its impact on worker performance.

Versatile conductive hydrogel orchestrating neuro–immune microenvironment for rapid diabetic wound healing through peripheral nerve regeneration

Diabetic wound (DW), notorious for prolonged healing processes due to the unregulated immune response, neuropathy, and persistent infection, poses a significant challenge to clinical management. Current strategies for treating DW primarily focus on alleviating the inflammatory milieu or promoting angiogenesis, while limited attention has been given to modulating the neuro-immune microenvironment. Thus, we present an electrically conductive hydrogel dressing and identify its neurogenesis influence in a nerve injury animal model initially by encouraging the proliferation and migration of Schwann cells. Further, endowed with the synergizing effect of near-infrared responsive release of curcumin and nature-inspired artificial heterogeneous melanin nanoparticles, it can harmonize the immune microenvironment by restoring the macrophage phenotype and scavenging excessive reactive oxygen species. This in-situ formed hydrogel also exhibits mild photothermal therapy antibacterial efficacy. In the infected DW model, this hydrogel effectively supports nerve regeneration and mitigates the immune microenvironment, thereby expediting the healing progress. The versatile hydrogel exhibits significant therapeutic potential for application in DW healing through fine-tuning the neuro-immune microenvironment.

Can Social Policy Alleviate Loneliness Among Older Adults? A Comparative Analysis of OECD Countries

ABSTRACT Loneliness in old age is a multifaceted issue influenced by personal, social, and environmental factors, necessitating a holistic approach. However, most research has predominantly focused on individual-level risk factors, with limited attention given to institutional factors such as social policy. This study investigated how social policies impact loneliness among older adults. Multi-level analysis was conducted using data from the 2017 wave of International Social Survey Programme, involving 6,337 older adults from 23 OECD countries. The analysis revealed that higher public spending on welfare and old-age pensions significantly reduces the likelihood of loneliness among older adults. These findings confirm the protective role of generous social policies in addressing old-age loneliness. They underscore the need for long-term changes in welfare systems to enhance the public response to the significant social risk posed by old-age loneliness.
