Abstract
Feather waste is a poultry by-product that is abundant, difficult to degrade, and creates an environmental problem. Feather protein is mainly composed of keratin, a structural protein with low digestibility. The effect of poultry feather meal prepared by NaOH as a Nitrogen source on the growth of the indigenous keratinolytic strain in the agar and the liquid medium was evaluated in this research. This study shows that all strains (Pseudomonas sp. PK-4, Bacillus cereus TD5B, and Bacillus cereus LS2B) can grow and produce clear zones around the colony. Medium containing 1% skim milk, commercial keratin, kampung, layer chicken feathers, and goose feathers were used to indicate that all strains could produce extracellular casein and keratinase enzymes. The strains can grow optimally in a liquid medium with feather hydrolysates, indicated by the increased turbidity (OD600) with a higher absorbance value. The highest growth occurred when strains grew with kampung chicken feather hydrolysate. Therefore, it can be concluded that the feather meals from local poultry feathers had potential as N-source for bacterial growth.

Abstract

Background
Both the close relationship processes and health model and the dyadic health influence model posit that beliefs about the relationship (e.g., relationship satisfaction) and influence strategies (e.g., social control) serve as mediators of health behavior change. The evidence for such mediation is limited.

Purpose
This study investigated two competing hypotheses that arise from these models: (1) perceived use of positive and negative social control (attempts to influence the partner’s behaviors) predict sedentary behavior (SB) indirectly, via relationship satisfaction; or (2) relationship satisfaction predicts SB indirectly, via positive and negative social control.

Methods
Data from 320 dyads (target persons and their partners, aged 18–90 years), were analyzed using mediation models. SB time was measured with GT3X-BT accelerometers at Time 1 (T1; baseline) and Time 3 (T3; 8 months following baseline). Relationship satisfaction and social control were assessed at T1 and Time 2 (T2; 2 months following baseline).

Results
Higher T1 relationship satisfaction among target persons predicted target persons’ reporting of higher T2 negative control from partners, which in turn predicted lower T3 SB time among target persons. Lower T1 relationship satisfaction among partners predicted target persons’ reporting of higher T2 perceived negative control from partners, which predicted lower T3 SB time among target persons. On average, both members of the dyad reported moderate-to-high relationship satisfaction and low-to-moderate negative control.

Conclusions
In contrast to very low levels of negative control, its low-to-moderate levels may be related to beneficial behavioral effects (lower SB time) among target persons reporting moderate-to-high relationship satisfaction.

Published: July 2022

Abstract

Background
Research indicates that perceived behavioral control (PBC) is an important determinant of behavior and that it is composed of perceived capability and opportunity. However, typical measurement of these constructs may be confounded with motivation and outcome expectations. Vignettes presented before questionnaire items may clarify construct meaning leading to precise measurement.

Purpose
The purpose of this study was to develop and validate measures of perceived capability and opportunity that parse these constructs from the influence of motivation and outcome expectations using vignettes.

Methods
Study 1 collected feedback from experts (N = 9) about the initial measure. Study 2a explored internal consistency reliability and construct and discriminant validity of the revised measure using two independent samples (N = 683 and N = 727). Finally, using a prospective design, Study 2b (N = 1,410) investigated test–retest reliability, construct and discriminant validity at Time 2, and nomological validity.

Results
After Study 1, the revised measure was tested in Studies 2a and 2b. Overall, the evidence suggests that the measure is optimal with four items for perceived capability and three for the perceived opportunity. The measure demonstrated strong internal consistency ( &gt; 0.90) and test–retest reliability (intraclass correlation coefficients [ICCs] &gt; .78). The measure also showed construct and discriminant validity by differentiating itself from behavioral intentions (i.e., motivation) and affective attitude (based on expected outcomes) (SRMR = 0.03; RMSEA = 0.06). It also demonstrated evidence of nomological validity as behavior 2 weeks later was predicted.

Conclusions
We recommend researchers use this tool in future correlational and intervention studies to parse motivation and outcome expectations from perceived capability and opportunity measurement.

Published: July 2022

AbstractObjectivesOur study assesses whether the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) offers any benefit over the original cytology classification, and measures interobserver agreement.MethodsFour cytopathologists retrospectively blindly classified preoperative cytology by MSRSGC from 101 resected salivary tumors. Consensus MSRSGC diagnoses were correlated with surgical pathology diagnoses and compared with the original cytology classification. Diagnostic parameters were calculated for both systems. Interobserver variability was assessed.ResultsThe original cytology classification vs MSRSGC had sensitivity, specificity, positive predictive value, and negative predictive value of 75.0% vs 78.3%, 97.1% vs 98.0%, 91.2% vs 94.7%, and 90.1% vs 90.0%, respectively. The original cytology classification risk of neoplasm (RON) was 91.7% for “negative for malignancy” and 100.0% for other categories. The MSRSGC RON was 71.4% in category II (nonneoplastic) and 100.0% in all other categories. The original cytology classification risk of malignancy (ROM) ranged from 0.0% for “atypical” to 100.0% for “positive for malignancy.” The MSRSGC ROM ranged from 0.0% in categories I (nondiagnostic) and III (nonneoplastic) to 100.0% in category VI (malignant). Weighted agreement using the MSRSGC was 92% (Gwet AC1, 0.84); unweighted agreement was 69% (Gwet AC1, 0.64). MSRSGC category IVA (benign neoplasm) was most likely to show interobserver agreement, with complete agreement in 67% of cases.ConclusionsThe MSRSGC performs similarly to the original cytology classification and shows relatively high interobserver agreement.

Published: July 2022

Abstract

Background and Aims
The process of domestication has driven dramatic shifts in plant functional traits, including leaf mass per area (LMA). It remains unclear whether domestication has produced concerted shifts in the lower-level anatomical traits that underpin LMA and how these traits in turn affect photosynthesis.

Methods
In this study we investigated controls of LMA and leaf gas exchange by leaf anatomical properties at the cellular, tissue and whole-leaf levels, comparing 26 wild and 31 domesticated genotypes of cotton (Gossypium).

Key Results
As expected, domesticated plants expressed lower LMA, higher photosynthesis and higher stomatal conductance, suggesting a shift towards the ‘faster’ end of the leaf economics spectrum. At whole-leaf level, variation in LMA was predominantly determined by leaf density (LD) both in wild and domesticated genotypes. At tissue level, higher leaf volume per area (Vleaf) in domesticated genotypes was driven by a simultaneous increase in the volume of epidermal, mesophyll and vascular bundle tissue and airspace, while lower LD resulted from a lower volume of palisade tissue and vascular bundles (which are of high density), paired with a greater volume of epidermis and airspace, which are of low density. The volume of spongy mesophyll exerted direct control on photosynthesis in domesticated genotypes but only indirect control in wild genotypes. At cellular level, a shift to larger but less numerous cells with thinner cell walls underpinned a lower proportion of cell wall mass, and thus a reduction in LD.

Conclusions
Taken together, cotton domestication has triggered synergistic shifts in the underlying determinants of LMA but also photosynthesis, at cell, tissue and whole-leaf levels, resulting in a marked shift in plant ecological strategy.

Published: July 2022

Abstract
Research on use of foraging patches has focused on why herbivores visit or quit patches, yet little is known about visits to patches over time. Food quality, as reflected by higher nutritional quality and lower plant defenses, and physical patch characteristics, which offer protection from predators and weather, affect patch use and hence should influence their revisitation. Due to the potentially high costs of moving between patches, fragmented habitats are predicted to complicate foraging decisions of many animals. We aimed to determine how food quality, shelter availability and habitat fragmentation influence tree reuse by a specialist folivore, the koala, in a fragmented agricultural landscape. We GPS-tracked 23 koalas in northern New South Wales, Australia and collated number of revisits, average residence time, and average time-to-return to each tree. We measured tree characteristics including food quality (foliar nitrogen and toxic formylated phloroglucinol compounds, FPCs concentrations), tree size, and tree connectedness. We also modeled the costs of locomotion between trees. Koalas re-visited isolated trees with high leaf nitrogen disproportionately often. They spent longer time in trees with high leaf nitrogen, and in large trees used for shelter. They took longer to return to trees with low leaf nitrogen. Tree connectivity reduced travel costs between patches, being either individual or groups of trees. FPC levels had no detectable effect on patch revisitation. We conclude that food quality and shelter drive koala tree re-visits. Scattered, isolated trees with nutrient-rich leaves are valuable resource patches for koalas despite movement costs to reach them.

Published: July 2022

AbstractReading disability (RD) can manifest itself as a word decoding problem or a reading comprehension problem. In the current study, we identified 3 subtypes of RD: poor decoders (PD), poor comprehenders (PC), and poor-in-both (PB). We found that PD had greater deficits in meta-linguistic skills such as phonological awareness, orthographic skills, and morphological skills than PC, whereas PC had greater deficits in listening comprehension than PD. In the brain, we also found different patterns of deficits during an auditory rhyming judgment task using functional magnetic resonance imaging. PD showed less activation than PC and age controls in the left dorsal inferior frontal gyrus (IFG) and pre-supplementary motor area (SMA), brain activation of which was correlated with phonological awareness and working memory. In contrast, PC showed less activation in the left fusiform gyrus than PD and age controls, which was correlated with reading comprehension fluency and morphological skill. Last, PB showed both PD’s and PC’s deficits, as well as additional deficits in the bilateral lingual gyri. Our findings contribute to revealing different neural signatures of poor decoding and poor comprehension, which are distinct disorders but co-occur very often. These findings implicate possibility and necessity of precise diagnosis and individualized intervention.
Estrogens rapidly shape synaptic and intrinsic properties to regulate the temporal precision of songbird auditory neurons

Published: July 2022

AbstractSensory neurons parse millisecond-variant sound streams like birdsong and speech with exquisite precision. The auditory pallial cortex of vocal learners like humans and songbirds contains an unconventional neuromodulatory system: neuronal expression of the estrogen synthesis enzyme aromatase. Local forebrain neuroestrogens fluctuate when songbirds hear a song, and subsequently modulate bursting, gain, and temporal coding properties of auditory neurons. However, the way neuroestrogens shape intrinsic and synaptic properties of sensory neurons remains unknown. Here, using a combination of whole-cell patch clamp electrophysiology and calcium imaging, we investigate estrogenic neuromodulation of auditory neurons in a region resembling mammalian auditory association cortex. We found that estradiol rapidly enhances the temporal precision of neuronal firing via a membrane-bound G-protein coupled receptor and that estradiol rapidly suppresses inhibitory synaptic currents while sparing excitation. Notably, the rapid suppression of intrinsic excitability by estradiol was predicted by membrane input resistance and was observed in both males and females. These findings were corroborated by analysis of in vivo electrophysiology recordings, in which local estrogen synthesis blockade caused acute disruption of the temporal correlation of song-evoked firing patterns. Therefore, on a modulatory timescale, neuroestrogens alter intrinsic cellular properties and inhibitory neurotransmitter release to regulate the temporal precision of higher-order sensory neurons.

Published: July 2022

Abstract
Many activities related to cybercrime operations do not require much secrecy, such as developing websites or translating texts. This research provides indications that many users of a popular public internet marketing forum have connections to cybercrime. It does so by investigating the involvement in cybercrime of a population of users interested in internet marketing, both at a micro and macro scale. The research starts with a case study of three users confirmed to be involved in cybercrime and their use of the public forum. It provides a first glimpse that some business with cybercrime connections is being conducted in the clear. The study then pans out to investigate the forum population's ties with cybercrime by finding crossover users, that is, users from the public forum who also comment on cybercrime forums. The cybercrime forums on which they discuss are analyzed and the crossover users’ strength of participation is reported. Also, to assess if they represent a sub-group of the forum population, their posting behavior on the public forum is compared with that of non-crossover users. This blend of analyses shows that (i) a minimum of 7.2% of the public forum population are crossover users that have ties with cybercrime forums; (ii) their participation in cybercrime forums is limited; and (iii) their posting behavior is relatively indistinguishable from that of non-crossover users. This is the first study to formally quantify how users of an internet marketing public forum, a space for informal exchanges, have ties to cybercrime activities. We conclude that crossover users are a substantial part of the population in the public forum, and even though they have thus far been overlooked, their aggregate effect in the ecosystem must be considered. This study opens new research questions on cybercrime participation that should consider online spaces beyond their cybercrime branding.
The vocalization of the red junglefowl is a signal of body size and individual health

Published: July 2022

Abstract
Bird songs are considered a sexually selected trait that can reflect the individual health of males as well as the vitality of potential mates and their competitors. Vocalization features should, therefore, be related to parasite load and body condition. Here, we performed a thorough acoustic analysis of the display calls of 9-month-old sub-adults and 18-month-old adults of pasture-raised red junglefowls Gallus gallus. We investigated whether the calls of pasture-raised red junglefowls can indicate body size and body condition, in addition to the influence of parasitic infection intensity on the expression of sexual traits. We found that frequency-related syllable parameters were significantly positively correlated with wing length in adults, whereas body weight was independent of both the frequency and temporal parameters of calls. In addition, we correlated parasitic load with the expression of sexually selected traits and discovered a positive association between the intensity of parasite infection and wing length in sub-adults, independent of vocal parameters. Overall, the results suggest that the vocalization of red junglefowls may convey reliable body size information, which will facilitate further studies of different vocal parameters in the transmission of bird vocalizations.

Abstract

OBJECTIVES
Many centres have recently adopted pulmonary valve (PV) preservation (PVP) during tetralogy of Fallot (ToF) repair. We sought to identify the midterm functional outcomes and risk factors for pulmonary regurgitation after this procedure.

METHODS
All patients undergoing PVP during transatrial–transpulmonary repair for ToF with PV stenosis at our institution between January 2007 and December 2020 were reviewed.

RESULTS
Overall, 73 patients were included. At the index surgery, the body surface area was 0.31 ± 0.04 m2, the age was 4.9 ± 2.9 months and the preoperative PV z-score was -3.02 ± 1.11. At a mean follow-up of 5.3 ± 2.7 years, the fractional area change of the right ventricle (RV) was 47.1 ± 5.2%, and the tricuspid annular plane systolic excursion z-score was -3.31 ± 1.89%. The 5-year freedom from moderate/severe PV regurgitation was 61.3% [95% confidence interval (CI): 48, 73%]. There was a significant correlation between RV function and moderate/severe PR at follow-up (R2: 0.08; P = 0.03). A comparison with a group of patients undergoing a transannular patch procedure (N = 33) showed superior outcomes for patients with PVP. The preoperative PV z-score and the degree of PR at discharge were risk factors for the early development of moderate/severe PR at follow-up [hazard ratio (HR): 0.64; 95% CI: 0.48, 0.86, P = 0.01 and HR: 2.31; 95% CI: 1.00, 5.36, P = 0.04, respectively]. A preoperative PV annulus z-score ≤ -2.85 was found to be predictive for moderate/severe PR at 5 years after PVP (HR: 2.56; 95% CI: 1.31, 5.01, P = 0.002).

CONCLUSIONS
A pulmonary valve preservation strategy during tetralogy of Fallot repair should always be attempted. However, a preoperative PV annulus z-score &lt; -2.85 and moderate/severe regurgitation upon discharge are risk factors for midterm pulmonary regurgitation.
How to organize an urban revolt in medieval Northern France: strategies of mobilization and political communication of craftsmen in Saint-Omer, 1305–1306
Authors: Serneels Hannah , Haemers Jelle 
Published: July 2022

Abstract
This article studies the strategies of mobilization and political communication of craftsmen during a revolt in Saint-Omer in 1305–6. An analysis of a written series of testimonies about the revolt shows that it was not a spontaneous happening, but the outcome of a strategically planned and cunningly carried out mobilization of men, money and means. The well-established practices of gathering, the remarkable culture of assembly and the efficiency of the mobilization of craftsmen of Saint-Omer demonstrate that these corporate associations had developed a sophisticated ‘repertoire of contention’ already around 1300. The repertoire was not new or unheard of, but rather strongly rooted in existing structures, corporate practices and venerable communal ideas of protecting the city.

Published: July 2022

Abstract

Objectives
Pre-pandemic research suggests assistance networks for older adults grow over time and are larger for those living with dementia. We examined how assistance networks of older adults changed in response to the onset of the COVID-19 pandemic and whether these changes differed for those with and without dementia.

Methods
We used three rounds of the National Health and Aging Trends Study. We estimated multinomial logistic regression models to test whether changes in assistance networks during COVID-19 (2019-2020) - defined as expansion, contraction, and adaptation - differed from changes prior to COVID-19 (2018-2019). We also estimated OLS regression models to test differences in numbers of helpers assisting with one (specialist) vs. multiple (generalist) domains before and during COVID-19. For both sets of outcomes, we investigated whether pandemic-related changes differed for those with and without dementia.

Results
Over all activity domains, a greater proportion of assistance networks adapted during COVID-19 compared to the pre-COVID-19 period (RRR = 1.19, p &lt; .05). Contractions in networks occurred for those without dementia. Transportation assistance contracted for those with and without dementia, and mobility/self-care assistance contracted for those with dementia. The average number of generalist helpers decreased during COVID-19 (β = -0.09, p &lt; .001).

Discussion
Early in the pandemic, assistance networks of older adults adapted by substituting helpers, by contracting to reduce exposures with more intimate tasks for recipients with dementia, and by reducing transportation assistance. Future research should explore the impact of such changes on the well-being of older adults their assistance networks.
