This paper analyzed the relationship between the gap selection and the types of oncoming vehicle in the process of pedestrians crossing the road. The oncoming vehicles were divided into large and small vehicle; six groups of pedestrians were recorded, young-male, mid-aged-male, old-male, young-female, mid-aged-female and old-female. The accepted gaps were recorded and analyzed using one-way ANOVA analysis. The results showed that, oncoming vehicles type had significant impact upon gap selection of pedestrians. A large oncoming vehicle had a shorter selected gap than a small oncoming vehicle. It is concluded that pedestrians have a smaller perceived velocity and overestimate the gap, large oncoming vehicle arrive conflict point. However, the overestimated gap was likely not safe to crossing the road. So, at no signal control intersection, a strict speed limit was necessary for large vehicle.

Drainage of surface water from the pavement structure is an important parameter for preserving the designed period and safety during the operation of the pavement structure. The paper presents research on the relationship between the efficiency of drains depending on the cross slope. When the correct selection of transverse slopes and the collection of rain runoff from the catchment area of the road, the safety of the operating conditions itself increases. By changing the transverse slope, the parameters in terms of water runoff speed and drain efficiency also change. During the analysis, this paper also took into account the hydrological parameters for the site where the section in question is located. The analysis in this paper aims to show how the correct selection of cross slopes of pavement structures can be of key importance for the efficiency of the drain, and thus the efficient drainage of surface water from the pavement structure.

The phonation types used in the young male role in Kunqu Opera were investigated. Two national young male role singers volunteered as the subjects. Each singer performed three voice conditions: singing, stage speech, and reading lyrics. Three electroglottogram parameters, the fundamental frequency, contact quotient, and speed quotient, were analyzed. Electroglottogram parameters were different between voice conditions. Five phonation types were found by clustering analysis in singing and stage speech: (1) breathy voice, (2) high adduction modal voice, (3) modal voice, (4) untrained falsetto, and (5) high adduction falsetto. The proportion of each phonation type was not identical in singing and stage speech. The relationship between phonation type and pitch was multiple to one in the low pitch range, and one to one in the high pitch range. The sound pressure levels were related to the phonation types. Five phonation types, instead of only the two phonation types (modal voice and falsetto) that are identified in traditional Kunqu Opera singing theory, were concomitantly used in the young male role’s artistic voices. These phonation types were more similar to those of the young female roles than to those of the other male roles in the Kunqu Opera.

The U.S. Forest Service has monitored longleaf pine cone production at sites throughout the southeastern United States for over 60 years. Data from the multi-decadal surveys have supported our understanding of the variability of stand-level cone production as it relates to environmental and ecological processes, and more broadly, how longleaf pine operates as a masting species. Cones from longleaf pine are counted each spring using visual surveys that follow a standard protocol. Rapid mast assessments have been proposed in the literature as an alternative to traditional methods, yet these approaches have not been examined for longleaf pine. In this study, I compared average cone production (using the traditional method) to the percentage of trees bearing cones (rapid assessment) to understand the relationship between these two mast measurements. I examined 29 years of data from 18 cone-monitoring sites containing 234 trees. Using simple linear models, I discovered the percentage of trees bearing cones explained 58–94% of the variance in log-average cone production across all sites. One-way ANOVA analysis revealed cone crops required for successful regeneration (25 + cones per tree) occurred when the percentage of trees bearing cones exceeded 90%, and the results from this study underscore the utility of a simple 90% threshold when determining a successful cone crop. While traditional cone-count methods should not be abandoned, I advocate for the use of rapid cone-crop assessments when a proxy approach is suitable.

Purpose – The purpose of this paper is to explore the relationship between psychopathic features as measured with the Psychopathy Checklist: Youth Version (PCL:YV) and behavioural and emotional functioning in young female offenders in custody. Design/methodology/approach – This is a quantitative interview study investigating the relationship with psychopathic traits, measured with the PCL:YV (Forth et al., 2003), and different psychological characteristics as well as AD/HD, self-harm, and childhood trauma in adolescent offenders across genders. Data were collected from a sample of 40 female and 40 male adolescents who were incarcerated in Victoria, Australia. Findings – Results indicated that the behavioural subscales of the PCL:YV were associated with externalising behaviours possibly underpinned by histories of abuse and substantiated child protection incidences. The presence of AD/HD was strongly associated with affective deficits suggesting that the PCL:YV may be identifying young females with AD/HD rather than core psychopathic traits. Findings also indicate that female-specific manifestations of manipulation are likely being misidentified as behavioural phenomena precluding clinical recognition as a core interpersonal trait. Significant dissimilarities with a young male comparison group were identified and are discussed within. Research limitations/implications – The sample size is very small and the results should be seen as an indication rather than generalising. Originality/value – Studies on female juvenile offenders is rare and this study adds to the literature on the construct of psychopathy and its relationship to psychosocial factors as well as associations with AD/HD, self-harm, and childhood trauma, among incarcerated adolescents.

With the growing aridity of the climate on the Don, it became necessary to improve the methodology for conducting the  breeding of spring durum wheat. The main method of obtaining the source material remains intraspecific step hybridization. Crossings were performed between genetically distant forms, differing in origin and required traits and properties. The use of chemical mutagenesis was a productive way to change the heredity of genotypes in terms of drought tolerance. When breeding for productivity, both in dry years of research and in favorable years, the most objective markers were identified — the size of the aerial mass, the mass of grain per plant, spike, and harvest index. The magnitude of the correlation coefficients between the yield per unit area and the elements of its structure is established. It was most closely associated with them in dry years, while in wet years it decreased. Power the correlation of the characteristics of the pair - the grain yield per square meter - the aboveground biomass averaged r = 0.73, and in dry years it was higher (0.91) than in favorable ones (0.61 - 0.70) , between the harvest and the harvest index - r = 0.81 (on average). In dry years, the correlation coefficient increased to 0.92. Research data confirms the greatest importance of the mass of grain from one ear and the plant in the formation of grain yield per unit area in both dry and wet years. In dry years, the correlation coefficient between yield and grain mass per plant was on average r = 0.80; in favorable years, r = 0.69. The relationship between yield and grain mass from the ear was greater — r = 0.84 and r = 0.82, respectively. Consequently, the breeding significance of the aboveground mass and the productivity of the ear, as a criterion for the selection of the crop, especially increases in the dry years. They were basic in the selection.

Background: Combining optimized cognitive (Alzheimer's Disease Assessment Scale- Cognitive subscale, ADAS-Cog) and atrophy markers of Alzheimer's disease for tracking progression in clinical trials may provide greater sensitivity than currently used methods, which have yielded negative results in multiple recent trials. Furthermore, it is critical to clarify the relationship among the subcomponents yielded by cognitive and imaging testing, to address the symptomatic and anatomical variability of Alzheimer's disease. Method: Using latent variable analysis, we thoroughly investigated the relationship between cognitive impairment, as assessed on the ADAS-Cog, and cerebral atrophy. A biomarker was developed for Alzheimer's clinical trials that combines cognitive and atrophy markers. Results: Atrophy within specific brain regions was found to be closely related with impairment in cognitive domains of memory, language, and praxis. The proposed biomarker showed significantly better sensitivity in tracking progression of cognitive impairment than the ADAS-Cog in simulated trials and a real world problem. The biomarker also improved the selection of MCI patients (78.8±4.9% specificity at 80% sensitivity) that will evolve to Alzheimer's disease for clinical trials. Conclusion: The proposed biomarker provides a boost to the efficacy of clinical trials focused in the mild cognitive impairment (MCI) stage by significantly improving the sensitivity to detect treatment effects and improving the selection of MCI patients that will evolve to Alzheimer’s disease.

Aim of review. Interpretation of published evidence on the relationship between the excessive belching syndrome and functional dyspepsia (FD) and their management in patient care.Key points. According to the Rome IV criteria of functional gastrointestinal disorders (FGID), excessive belching in the absence of other dyspeptic symptoms is to be considered a manifestation of the excessive belching syndrome, which can be of gastric or supragastric nature. Combination of high-resolution manometry and impedancemetry allows an accurate diagnosis of belching and selection of optimal treatment strategy. Belching complicated by other symptoms of dyspepsia is to be considered yet another FD symptom according to the Rome IV criteria of FGID. Prokinetics are recommended to relieve belching in such cases.Conclusion. Understanding the relationship between the excessive belching syndrome and FD requires further research.
