Cognitive Abilities in Schizoid Personality Disorder with and without Borderline Intellectual Functioning: The Burden in Psychopathology
Get PDFBackground: Borderline intellectual functioning (BIF) and schizoid personality disorder (Schizoid PD) are clinical conditions under-researched and poorly understood. The principal aim of this retrospective study was to investigate cognitive abilities in people with BIF and Schizoid PD. Clinical, demographic, and neuropsychological data of forty-seven Schizoid PD participants, with an average age of 35, were analyzed. The sample split into two groups: Schizoid PD with BIF (BIF+: n = 24; intelligence quotient – IQ range: 71-84) and Schizoid PD without BIF (BIF-: n = 23; IQ range: 89-121). A descriptive analysis of the clinical and demographic characteristics of the two groups was performed.
Methods: Neuropsychological measures (Wechsler Adult Intelligence Scale-Revised – WAIS-R IQ, factor index, subtest scores) and cognitive performance deficits in the two groups were compared using parametric and non-parametric tests, as necessary. Correlation coefficients were calculated for relationships between variables. Regression analyses were conducted to identify predictors associated with negative outcomes, such as substance use behavior.
Results: The results revealed that the cognitive profile of BIF+ deviated significantly from that observed in BIF-. Peculiar BIF+ dysfunctions were found in the domains of verbal and perceptual reasoning, attention, memory, processing speed, planning, and problem-solving. The verbal IQ had the highest discriminative value for the presence of BIF in patients with Schizoid PD.
Conclusions: The BIF condition and the verbal comprehension index were the predictors most associated with substance use behavior. Early identification of BIF should be relevant to planning targeted intervention strategies to improve daily life skills and outcomes
Sustainable Construction Materials for Bangladesh in Tropical C-Limate, Literature Review

Metagenomic Analysis during Co-Digestion Buffalo Sludge and Tomato Pomace Post Thermal Stress: A Case Study
Get PDFThe tomato industry and buffalo farming generate waste, including sludge (BS) and tomato pomace (TP), which can significantly impact their economic and environmental sustainability. The case study tracked changes in microflora composition after a thermal shock during anaerobic co-digestion. The inoculum-to-substrate ratio was 0.5 based on volatile solid content under mesophilic conditions. An Automatic Methane Potential Test System was used to monitor the process before and after thermal stress (50°C) occurred for three days. Next-generation sequencing analyzed the bacterial and archaeal communities. The pH decreased, and methane production plateaued due to the high volatile solid content (87 g/L). After thermal stress, the pH returned to neutral, and the batch resumed biogas production. The cumulative CH4 production reached 3,115 Nml. The biogas had a maximum methane peak of 78.5% compared to 58.4% in BS. The taxonomic classification showed that Firmicutes (51.7%) and Bacteroidetes (29.9%) represented 81.6% of the total OTUs among the bacteria. Fonticella, the most abundant Clostridiaceae (average 4.3%), was absent in BS and increased (up to 17.1%) in TP during methane production. Methanocorpusculum was the most abundant in the archaeal community. However, Metanosarcina showed a stronger correlation with methane production. Brief thermal stress significantly altered bacterial and archaeal populations and allowed to resume biogas production
Attitudes on Policy and Punishment: Opposition to Inequality-Based Government Aid Predicts Support for Capital Punishment
Get PDFObjective: There exists a well-developed body of research on the attitudinal correlates of support for capital punishment. Among the most robust of these is racism and racial attributions. The study presented here was designed to explore whether policy prescriptions reflective of racial attitudes can predict support for capital punishment.
Method: Data come from the 2018 iteration of the NORC General Social Survey. The dependent variable is a dichotomous measure of support for the death penalty for people convicted of murder. The independent variable is a 5-level Likert-type item of support for government aid to Blacks to help overcome discrimination. Binary logistic regression was used to analyze the relationship between variables net of standard controls.
Results: Over 63 percent of the total sample supported the death penalty. Support among those strongly favored government aid to Blacks was 41 percent. Support among those who strongly rejected aid to Blacks was 78 percent. Results of the regression analysis showed each decrease in the level of support for government aid to Blacks was associated with an 18.6 percent increase in the likelihood of supporting the death penalty.
Conclusion: Capital punishment support is not simply a function of abstract, hypothetical racial attitudes. The findings reported here suggest support for the death penalty is associated with concrete policy prescriptions that maintain racial inequalities. Given that capital punishment continues in large part due to public support, it should be recognized that this support is based on a desire to maintain racial inequalities through government action
A Study on the Effects of Biodiversity and Conservation Efforts on Community Health in the Sunderban Area of Eastern India
Get PDFThe Sunderbans, located at the southernmost tip of the Bay of Bengal, is a UNESCO World Heritage site renowned for its mangrove extent encompassing tidal rivers, mudflats, and islands. As the home of the Royal Bengal Tiger and countless humans, it represents the ecological centre of Eastern India. The primary objective of this study is to analyse community participation in Sunderbans conservation strategies. We are in a position to identify the primary catalysts and inhibitors of such community engagement by understanding the correlation between active conservation participation and health outcomes. The essence of the study emphasises the community's awareness of environmental factors that affect the health. Our ultimate objective is to design a framework that clarifies the connections between conservation and health initiatives in areas of high biodiversity. Using a mixed-methods approach, quantitative biodiversity metrics were derived using species richness, evenness, and Simpson's Diversity Index, and health data were gathered using standardised community health surveys that focused on disease prevalence, nutrition status, and sanitation practises. Twenty sites with differing degrees of community-based conservation activities provided the data. Using sophisticated statistical methods, such as multivariate regression analyses and non-metric multidimensional scaling, patterns and correlations between biodiversity and health indicators were identified. Preliminary results indicated a correlation between biodiversity metrics and specific health indicators. There was a 16.8% decrease in waterborne maladies and a 12.1% increase in nutritional diversity among community members in areas with greater biodiversity. Additionally, areas with robust community-based conservation activities demonstrated a 19.8% increase in biodiversity and community health metrics in comparison to areas with minimal to no conservation activities. Our findings highlight the necessity of merging conservation and health agendas, arguing for an integrative strategy in biodiverse regions. It is in the best interest of global stakeholders to recognise and exploit such potential in comparable ecologies
Hemostatic Gelatin-Alginate Hydrogels Modified with Humic Acids and Impregnated with Aminocaproic Acid
Get PDFThe work is devoted to the development of safe and biocompatible multicomponent gelatin-alginate hydrogels modified with humic acids (HA) and impregnated with the antifibrinolytic agent aminocaproic acid (АА).These hydrogels are designed to be effective hemostatic materials with anti-inflammatory properties and the ability to deliver in less than 30 seconds to deep and hidden areas of hemorrhages. Studies of the crystal structure by X-ray diffraction analysis and non-covalent interactions of molecules by Fourier transform infrared spectroscopy of the developed hemostatic gelatin-alginate hydrogels modified with bactericidal and anti-inflammatory humic acids made it possible to identify the optimal concentrations of HA from 2.5 wt.%. up to 5 wt.%. At such concentrations of HA, gelatin-alginate hydrogels have a semicrystalline structure. Due to non-covalent bonds between polymer chains, they are thermo-responsive with a gel-sol transition temperature of about 37 °C. Impregnation of these hydrogels with aminocaproic acid led to an almost threefold increase in their swelling, which facilitated the dissolution of AA in the hydrogels and its subsequent delivery to the wound. Experiments simulating the transmembrane transport of aminocaproic acid from the developed gelatin-alginate hydrogels confirmed their ability to rapidly deliver up to 494± 3 mg of AA from 5 ml of hydrogel to the wound
Parental Factors Related to COVID-19 Prevention Behavior in Children with Intellectual Disability: Partial Least Square Structural Equation Modeling
Get PDFEfforts to prevent COVID-19 in children with intellectual disability require the role of parents. Even though the vaccine has been implemented, the most important effort is to implement health protocols. Implementing health protocols cannot be separated from knowledge, attitudes, intentions, subjective norms, and social support from parents. This research aims to determine the influence of knowledge, attitudes, intentions, subjective norms, and social support on the COVID-19 prevention behavior of parents of children with intellectual disability. This type of research is descriptive correlational research, and the developed model is validated using the partial least squares structural equality modeling (PLS-SEM) approach based on data collected from 100 parents of children with intellectual disabilities taken using purposive sampling at Semarang Municipal Special Schools.The study results show that parental characteristics, namely education, influence attitudes, which can ultimately affect parental intentions. Parental education also affects social norms, namely social support and subjective norms, which can determine COVID-19 prevention behavior. Parental education is a priority in public health strategies because it can directly shape attitudes, intentions, and social norms that can improve the health of children with intellectual disabilities. Health programs and education for parents must be focused and carried out consistently and continuously

Results: Results revealed (1) a moderate degree of availability of administrative and leadership requirements for inclusion of children with disabilities in the kindergarten stage; (2) higher ranking of items indicating school administrations’ awareness of dissemination of an inclusive culture than those indicating their efforts to provide the material and human resources necessary for the inclusion processes; (3) teachers’ specialization was not statistically significant but years of experience was significant in comprehending administrative efforts.
Conclusion: the study provided a clear vision of the administrative and leadership requirements for the inclusion of children with disabilities in the kindergarten stage from their teachers' point of view and the variables that may affect the degree of availability of these requirements
Conditions of Formation of α- and β-Modifications of Ge3N4 and Preparation of Germanium Oxynitride Dielectric Films
Get PDFThe binary compound of germanium with nitrogen (Ge3N4) is used in various fields of science and technology. Among the experimentally discovered and theoretically predicted crystal modifications of Ge3N4 at ordinary pressures and temperatures, only the α- and β-phases of the nitride are stable. There are conflicting data in the literature on the conditions for the formation of these phases. The main methods for obtaining Ge3N4 are the nitridation of elemental germanium and its dioxide with ammonia. The present work studied the influence of the degree of humidity of ammonia on the possibility of the formation of pure α- and β-phases and their mixtures. It is shown that it is possible to obtain nitride with practically any ratio of these phases by varying degrees of humidity and the temperature of the process. During the process, the formation of germanium nitride is accompanied by its simultaneous evaporation. Oxidation with water vapors also produces volatile monoxide. Simultaneous evaporation of germanium nitride and oxide results in the deposition of a film of germanium oxynitride in the cold zone of the reactor. This film is a germanium oxynitride used in microelectronics as a dielectric layer in Metal-Insulator-Semiconductor systems
