No-Antibiotic-Pectin-Based Treatment Differently Modified Cloaca Bacteriobiome of Male and Female Broiler Chickens

As the information about the effect of pectin prebiotics on chicken gut microbiota is scarce, by using high throughput metagenomic sequencing with Illumina Miseq we examined the cloaca bacteriobiome of male and female chickens receiving antibiotic- or pectin-containing drinking water. The bacteriobiome was dominated by two phyla (Firmicutes and Proteobacteria) and three classes (Clostridia, Bacilli and Gammaproteobacteria), with the difference displayed by the relative abundance of 42 OTUs. At the level of the major dominant OTUs, prebiotic supplementation drastically increased Enterococcus abundance (from 0 to 11% and 23% in males and females, respectively). The better feed use efficiency and growth performance of the pectin-receiving chickens implied their better health and corroborated putative beneficial role of the altered bacteriobiome, although its ecophysiological and/or pathogenic importance could not be readily inferred. Notably, the gut microbiota response to antibiotics showed more sex-related differential OTUs as compared to the pectin prebiotic (19 vs. 4), suggesting different mechanisms of the studied supplementations in shaping the gut bacteriobiome in different sexes. Therefore, we recommend targeting sex as a separate factor in interventional studies to account for sex-specific peculiarities in the microbiome response and taking into account the male/female ratio of industrial flocks prior to choosing a production technology. The studied prebiotic (pectin) can be used in developing new pre/symbiotic preparations and supplementation regimes as alternatives to antibiotics for stimulating broiler chicken production.

On the Influence of Interlayer Nonuniformity on Contact Characteristics during the Interaction of a Pipe and a Rigid Cylindrical Insert

Contact problem for viscoelastic aging pipe with a longitudinally nonuniform thin elastic internal coating and a rigid cylindrical insert is considered in the paper. The basic integral equation with integral operators of different types (mixed integral equation) is given. It's analytical solution for contact stresses in insert area is presented. The solution is constructed in such a way that the function describing the inner coating nonuniformity is distinguished by a separate factor. This fact allows one to perform accurate calculations even in cases where the coating properties are described by rapidly changing and even discontinuous functions. Other known analytical methods do not allow one achieving such a results.

The ICD-11 Personality Disorder Trait Model Fits the Kurdish Population Better Than the DSM-5 Trait Model

The ICD-11 Classification of Personality Disorders and the DSM-5 Alternative Model of Personality Disorders (AMPD) operate with trait domains that contribute to the individual expression of personality disturbance (i.e., negative affectivity, detachment, dissociality, disinhibition, anankastia, and psychoticism). To date, these trait frameworks have not been investigated sufficiently in Middle Eastern cultures. Thus, the present study explored the structure of the ICD-11 and AMPD personality disorder (PD) trait domains in a large mixed sample from the Kurdistan zone of Iran. The ICD-11 and AMPD trait domains were operationalized using empirically supported algorithms for the Personality Inventory for DSM-5 (PID-5). The PID-5 was administered to a large mixed sample (N = 3,196) composed of 2,678 community and 518 clinical participants. Structural validity was investigated using Exploratory Factor Analysis (EFA), whereas differential construct validity was explored by comparing clinical and community scores. Model fit and the expected factor structure were deemed appropriate for the ICD-11 trait model, but less adequate for the DSM-5 trait model (i.e., disinhibition did not emerge as a separate factor). All domain and facet scores showed significant differences between clinical and community subsamples with moderate to large effects, mostly for disinhibition and dissociality/antagonism while least for anankastia. The findings of the present study may suggest that the ICD-11 trait model is more cross-culturally fitting than the DSM-5 AMPD trait model, at least with respect to a large mixed sample from the region of Kurdistan. Accordingly, there is evidence for using PID-5 data for WHO ICD-11 purposes in this part of the World.

Socially Desirable Responding in Experience Sampling

Experience sampling often makes use of items that are similar to personality questionnaire items. Arguably, this opens up for item-popularity effects, where some respondents react to the items’ level of evaluative phrasing, causing a separate factor. Gauging the risk of item popularity effects in experience sampling is important since the multifactorial aspect of the responses to the items may cause spurious correlations. We investigate this in one original study and two existing datasets. The results reveal that evaluativeness in experience sampling items creates the same type of problems as in self-rating inventories. We conclude that personality researchers need to be aware that the experience sampling method is not vaccinated against socially desirable responding, and that careful phrasing of items promotes purer personality measures. This allows for more optimal testing of theoretical models of personality, as the fit between data and model will not concern variance in socially desirable responding but in the relevant constructs.

Controllable Fabrication of Large-Size Defect-Free Domains of 2D Colloidal Crystal Masks Guided by Statistical Experimental Design

Large defect-free domains of a hexagonal packed monolayer of silica spheres with the size of 4000 µm2 were successfully prepared by dual-speed spin coating. Experimental design and statistical analysis instead of the traditional ‘changing one separate factor at a time’ (COST) approach were employed to guide the implementation of the experiments. With its assistance, the hexagonal-close-packed (HCP) percentage was elevated to 84% in this study. Furthermore, almost all the samples with parameters in the selected ranges possessed more than a 60% HCP percentage. In addition, the optimal values for parameters of the suspension concentration, the first rotation speed, and the spinning time to obtain well-ordered silica spheres arrays were also identified as 30 wt.%, 1000 rpm and 20 s, respectively.

Understanding Consumer Enchantment via Paranormal Tourism: Part II—Preliminary Rasch Validation

Situational-enchantment is a hypothesized arousal state encompassing a potent sense of connection or oneness with a “transcendent power or ultimate reality.” Qualitative research previously suggested that this individual difference involves dissonance around ideations with competing “Emotional, Sensorial, Timeless, Rational, and Transformative” themes. We tested this presumed phenomenology via an online convenience sample of 79 men and 101 women who reported memorable ghostly experiences during a paranormal tour within the last 12 months. Respondents provided a global enchantment rating of their anomalous experiences, as well as selected specific descriptors from a set of 30 items on an adjective checklist (ACL). Analyses revealed that 21 items on the Enchantment-ACL formed a Rasch hierarchy of generally “pleasant” themes that was free of response biases related to age, sex, and latency (time since the “enchanting” experience). This structured sequence contained all five experiential themes, and the resulting Enchantment-ACL measure of this phenomenon showed good internal reliability (Rasch reliability = .82) and a positive correlation with global enchantment ratings ( r = .51, p < .001). The other nine items formed a separate factor containing overtly “unpleasant” ideations. We discuss the results within a cognitive dissonance framework for situational-enchantment, although future research must explore potential nuances related to the construct’s dimensionality and the specific role of pleasant versus unpleasant ideations.

Untangling the animacy organization of occipitotemporal cortex

Some of the most impressive functional specialization in the human brain is found in occipitotemporal cortex (OTC), where several areas exhibit selectivity for a small number of visual categories, such as faces and bodies, and spatially cluster based on stimulus animacy. Previous studies suggest this animacy organization reflects the representation of an intuitive taxonomic hierarchy, distinct from the presence of face- and body-selective areas in OTC. Using human fMRI, we investigated the independent contribution of these two factors – the face-body division and taxonomic hierarchy – in accounting for the animacy organization of OTC, and whether they might also be reflected in the architecture of several deep neural networks. We found that graded selectivity based on animal resemblance to human faces and bodies masquerades as an apparent animacy continuum, which suggests that taxonomy is not a separate factor underlying the organization of the ventral visual pathway.

Measuring Beliefs about Teaching for Creativity

Background/Context Beliefs about teaching for creativity is a newer area of empirical investigation in education. Purpose The purpose of the quantitative study was to measure teachers’ domain-specific beliefs about teaching for creativity, piloted for the first time in this study, and compare these beliefs with domain-general beliefs about creativity. Subjects The study subjects were preservice and practicing teachers enrolled in bachelor's, master's, and doctoral (PhD and EdD) education programs within a private university located in the northeastern United States. Research Design This study surveyed a convenience sample of preservice and practicing teachers’ beliefs about creativity and their beliefs about teaching for creativity to examine their creative self-efficacy, growth and fixed creative mindsets, desirability of creativity for teaching success, and valuing creativity for student learning. Data Collection and Analysis A total of 149 students completed a measure on beliefs about creativity (domain-general) and beliefs about teaching for creativity (domain-specific). Exploratory factor analysis was conducted to examine potential newly aligned items and factors with a change in wording. Results The factor structure of the Fixed Creative Mindset items, Creative Self-Efficacy items and Desirability items was stable when rewording them to represent teacher perspectives. The Growth Creative Mindset items do not show the same stability, but two of the items seem to be related to a single factor, which is evidence that these items are functioning well. The newly worded Value items loaded on a separate factor, with only one cross loading. Educators rated themselves high in most areas, and low in the area of Fixed Creative Mindset. The results indicate that the Beliefs About Teaching for Creativity scales are reliable, with significant correlations among factors. Recommendations We propose research and policy recommendations to further examine the complex relationship between teachers’ beliefs about teaching for creativity and their pedagogical practices, especially in the area of growth and fixed creative mindset.

Wear of elastic tube with nonuniform coating by rigid bush

This article is devoted to the statement and construction of analytical solution of the wearcontact problem for a rigid bush and elastic pipe with a coating in the case when the coating is nonuniform. The presence of nonuniformity leads us to the necessity of constructing a solution in a special form over special functions, since standard methods does not allow us to effectively take into account the complex properties of the coating. Analytical representation for contact stresses under the bush is presented in series with separate factor, which connect with complex properties of coating. This allows provide effective calculation even if these properties are described by rapidly changing or discontinuous functions. It is also shown that contact stresses will be negligible over time.
