The impact of organizational politics on work engagement—the mediating role of the doctrine of the mean

Introduction Events Theory posits that the perception of organizational politics affects job attitudes. The purpose of this study was to answer the question: does organizational politics have a similar impact on Chinese individuals who adhere to the doctrine of the mean? Methods We collected survey data from 3,059 library personnel in 36 Chinese university libraries and conducted analysis using the Analytic Hierarchy Process. Results The results showed that the perception of organizational politics reduces employee work engagement. However, this impact exhibits heterogeneity. For newly recruited employees and employees aged 50 and above who are nearing retirement, the impact of organizational politics on work engagement is relatively small. Conversely, for employees aged 30–50, organizational politics has a significant negative impact. Furthermore, the doctrine of the mean moderates the impact of organizational politics on work engagement, mitigating its negative effects. Discussion The conclusions offer new insights into enhancing employee work motivation. The library should take more measures to safeguard employee rights to enhance work motivation.
Release of Pro-Inflammatory/Angiogenic Factors by Retinal Microvascular Cells Is Mediated by Extracellular Vesicles Derived from M1-Activated Microglia

The interactions between the neuronal and vascular sides of the retina during diabetic retinopathy (DR) have gained increasing attention. Microglia is responsible for the immune response to inflammation inside the retina, which could be mediated by paracrine signals carried by extracellular vesicles (EVs). We aimed to characterize EVs released from immortalized human microglial cells in inflammation and investigate their effects on the retinal microvasculature and the anti-inflammatory potential of thiamine in this context. M1 pro-inflammatory polarization in microglia was induced through a cytokine cocktail. EVs were isolated from the supernatants, characterized, and used to stimulate human retinal endothelial cells (HRECs) and pericytes (HRPs). Microvascular cell functions and their release of pro-inflammatory/angiogenic factors were assessed. M1-derived EVs showed increased content of miR-21, miR-155, CCL2, MMP2, and MMP9, and enhanced apoptosis, proliferation, migration, and ROS production in HRPs and HRECs. IL-1β, IL-6, MMP9, CCL2, and VEGF release increased in HRPs exposed to M1-derived EVs, while HRECs showed augmented IL-6, Ang2, VEGF, and PDFG-B. Addition of thiamine to M1-microglial cultures reverted most of these effects. In conclusion, M1-derived EVs stimulate functional changes and secretion of pro-inflammatory/angiogenic molecules in microvascular cells, exacerbating inflammatory damage and retinopathy features. Thiamine added to microglia exerts anti-inflammatory effects.
Exsolution and crystal chemistry of the sodium mica wonesite

Transmission electron microscopy; wonesite from the Post Pond Volcanics, Vermont. A new method of deriving the chemical compositions of the phases in fine lamellar intergrowths from electron microscope X-ray analyses is described. The method, which utilizes the bulk chemical analysis of the intergrowth as a standard, is used to derive the chemical compositions of the intergrown talc and mica. The exsolution of wonesite provides a structural analogy for amphibole exsolution phenomena that involve the amphibole A-site. --Modified journal abstract.
From the projected to the transmitted image: the 2.0 construction of tourist destination image and identity in Catalonia

This thesis aims to explore online projected and perceived images of a tourist destination, to assess their mutual correspondence, and to shed light on the role of online user-generated images in destination image formation. It also seeks to analyse the spatial distribution of image by tourists and the complex image identity issues concerning a destination. To achieve this, online image sources regarding the case study of Catalonia were analysed through massive computerized quantitative content analysis of some 25,000 travel blog and review entries (perceived image) and around 3,000 official tourism webpages (projected image). The results showed significant dissonance between tourists’ images and official images of the destination in several aspects, notably its attraction factors and cultural identity. Tourists' destination images were found to be greatly concentrated on certain elements and spaces. Finally, this thesis proposes the concept of "transmitted image" to reflect the new central role of tourists’ online images in the creation, dissemination and formation of destination image. Keywords: tourist destination image; destination identity; online image; perceived image; projected image; transmitted image; travel blog; travel review; official tourism websites; Web 2.0; quantitative content analysis; Catalonia.
Turnover intention of nurses in public hospitals and its association with quality of working life: a cross-sectional survey in six provinces in China

Objectives High turnover intention can exacerbate the workforce shortage of nurses. This study aimed to determine the level of turnover intention of public hospital nurses in China and its associated factors. Methods A cross-sectional questionnaire survey of 2,863 nurses was conducted in 48 public hospitals across six provinces in mainland China, measuring the sociodemographic (gender, age, marital status, and monthly basic salary) and work characteristics (professional title, workload, night sleep deprivation, and workplace violence) of respondents, their quality of working life (QWL), and turnover intention. Multivariate logistic regression models were established to determine the association between QWL and turnover intention after adjustment for variations of the sociodemographic and work characteristics. Results Overall, 42.8% of respondents reported turnover intention. Higher QWL scores (AOR = 0.824 for job and career satisfaction, p < 0.001; AOR = 0.894 for professional pride, p < 0.001; AOR = 0.911 for balance between work and family, p < 0.05) were associated with lower turnover intention. Workplace violence was the strongest predictor of higher turnover intention (AOR = 3.003–4.767) amongst the sociodemographic and work characteristics, followed by an age between 30 and 40 years (AOR = 1.457 relative to <30 years), and night sleep deprivation (AOR = 1.391–1.808). Senior professional title had a protective effect (AOR = 0.417 relative to no title) on turnover intention. Conclusion High levels of turnover intention are evident across China in nurses employed by public hospitals, in particular in those aged between 30 and 40 years. Low QWL and poor work environment are significant predictors of turnover intention.
Impact of Season on Intestinal Bacterial Communities and Pathogenic Diversity in Two Captive Duck Species

Simple Summary The gut bacterial community of two captive ducks was investigated in this study across seasons. It was discovered that the composition of gut bacteria was significantly affected by seasonal variations, with greater diversity in winter. Different seasons yielded different biomarkers, with the majority found in winter when a more intricate bacterial network structure was seen. Ten important pathogenic bacterial species were discovered and appeared to be more abundant in the summer. The presence of significant pathogenic bacteria was demonstrated by this study, raising concerns for captive animals, and shedding light on how gut bacterial composition is affected by seasonal fluctuations. Abstract Vertebrates and their gut bacteria interact in complex and mutually beneficial ways. The intestinal microbial composition is influenced by several external influences. In addition to food, the abiotic elements of the environment, such as temperature, humidity, and seasonal fluctuation are also important determinants. Fecal samples were collected from two captive duck species, Baikal teal (Sibirionetta formosa) and common teal (Anas crecca) across four seasons (summer, autumn, winter, and spring). These ducks were consistently fed the same diet throughout the entire experiment. High throughput sequencing (Illumina Mi-seq) was employed to analyze the V4–V5 region of the 16sRNA gene. The dominant phyla in all seasons were Proteobacteria and Firmicutes. Interestingly, the alpha diversity was higher in winter for both species. The NMDS, PCoA, and ANOSIM analysis showed the distinct clustering of bacterial composition between different seasons, while no significant differences were discovered between duck species within the same season. In addition, LefSe analysis demonstrated specific biomarkers in different seasons, with the highest number revealed in winter. The co-occurrence network analysis also showed that during winter, the network illustrated a more intricate structure with the greatest number of nodes and edges. However, this study identified ten potentially pathogenic bacterial species, which showed significantly enhanced diversity and abundance throughout the summer. Overall, our results revealed that season mainly regulated the intestinal bacterial community composition and pathogenic bacteria of captive ducks under the instant diet. This study provides an important new understanding of the seasonal variations in captive wild ducks’ intestinal bacterial community structure. The information available here may be essential data for preventing and controlling infections caused by pathogenic bacteria in captive waterbirds.
Internal Model With Interaction Gain Explains Plantar Ground Reaction Force Changes According to the Plantar Surface Area

To maximize the clinical benefit of sensory interventions, it is important to quantitatively anticipate their effects on motor output. However, existing internal models do not represent the complete sensorimotor loop, which is necessary to extract a relationship between the sensory intervention and the change in motor output. In this study, we propose a new internal model with an interaction gain, to complete the sensorimotor loop and anticipate the effect of sensory interventions on motor output. To demonstrate the efficacy of the proposed internal model, we measured the change in ground reaction force with the unilateral changes in plantar surface area (i.e., change in the contacting area of the foot sole). Sixteen young healthy subjects (average age: 23) participated in the experiment. The interaction gain, expressed as a function of the plantar contact area ratio, successfully explains the change in plantar ground reaction force (<inline-formula> <tex-math notation="LaTeX">${R}^{{2}}$ </tex-math></inline-formula> = 0.89). Also, motor and sensory gains, calculated based on the proposed internal model, are correlated with subjects’ weight (<inline-formula> <tex-math notation="LaTeX">${R}^{{2}}$ </tex-math></inline-formula> = 0.98) and plantar tactile sensitivity (<inline-formula> <tex-math notation="LaTeX">${R}^{{2}}$ </tex-math></inline-formula> = 0.21), respectively. Experimental results suggest that the new internal model with interaction gain can anticipate the change in motor output based on the change in sensory intervention. We expect that the new internal model with interaction gain will help determine the optimal parameters of sensory intervention and enhance its efficacy for motor rehabilitation.
A Stocking-Rate Guide for Beef Production on Blue-Grama Range.

A few of the possibilities that exist for elevating the status of the discipline called range management to that of a profession and for developing professionalism among range managers have been presented. There are numerous others. Many members of the discipline are worried about the image of Range Management. Based on the criteria presented, it is evident that the Society and the members of the vocation must work to improve the discipline before there can be public recognition. Most importantly, we need to develop a sense of professionalism among all range managers and particularly within the ASRM. We may be placing too much emphasis on selling an image (Newport, 1968). By so doing, we are treating the fever rather than the infection. A poor image is the fever; poor performance and an inadequately defined area of expertise are the infection. A salesman must have a salable product before he can sell anything and range managers, at present, do not have much of a product (a well demonstrated performance capability and an area of expertise) to sell.

The Duality of Adiponectin: The Role of Sex in Atherosclerosis

The hormone adiponectin has many beneficial effects in atherosclerosis, as gene deficiency in adiponectin or its receptor has shown detrimental effects on plaque burden in mice. Our objective was to understand the potential roles adiponectin deficiency has on aortic plaque content, inflammation, and markers of cardiovascular disease according to sex and age. To study the influence of adiponectin status on sex and atherosclerosis, we used young male and female adipoq−/− apoe−/−, adipoq+/−apoe−/−, and apoe−/− mice, which were given a high-fat diet (HFD). Even a 50% reduction in the expression of adiponectin led to a plaque reduction in males and an increase in females compared with apoe−/− controls. Changes in plaque were not attributed to changes in cholesterol or cardiovascular disease markers but correlated with inflammatory markers. Plaque reduction in males was associated with reduced monocyte chemoattractant protein 1 (MCP1) and increased colony stimulating factor 3 (CSF3), while the increase in plaque in females correlated with the opposite effect in these markers. In old mice, both adiponectin-deficient genotypes and sexes accumulated more plaque than their respective apoe−/− controls. The increase in plaque with adiponectin deficiency according to age was not explained by a worsening lipid profile but correlated with increased levels of C-C motif chemokine ligand 5 (CCL5). Overall, our study uncovered genotype-specific effects that differed by sex and age of adiponectin deficiency in atherosclerosis.
Late Ordovician Mass Extinction: Earth, fire and ice

ABSTRACT The Late Ordovician Mass Extinction was the earliest of the ‘big’ five extinction events and the earliest to affect the trajectory of metazoan life. Two phases have been identified near the start of the Hirnantian period and in the middle. It was a massive taxonomic extinction, a weak phylogenetic extinction and a relatively benign ecological extinction. A rapid cooling, triggering a major ice age that reduced the temperature of surface waters, prompted a drop in sea level of some 100 m and introduced toxic bottom waters onto the shelves. These symptoms of more fundamental planetary processes have been associated with a range of factors with an underlying driver identified as volcanicity. Volcanic eruptions, and other products, may have extended back in time to at least the Sandbian and early Katian, suggesting the extinctions were more protracted and influential than hitherto documented.

Background – Diagnosis of adverse food reaction (AFR) is based on an eight week elimination diet (ED) and is conﬁrmed by relapse upon re-challenge with the previously fed diet. Hydrolysed EDs are commonly used for this purpose. Objective – To evaluate the commercially available hydrolysed ﬁsh protein and rice starch ED Farmina UltraHypo (FUH) for the diagnosis of feline AFR.
Quality Characteristics of Beef Patties Fortified with Husk Tomato and the Effect on Tannic Acid-Induced Anaemia in Rats

The study evaluated the properties of beef burgers prepared with different concentrations of husk tomato (HT) powder at levels of 2.5%, 5%, and 10% as a natural source of bioactive compounds and also assessed the effectiveness of the powder in the treatment of anaemia. Rats were classified into the negative control group and anaemic rats that were positive control (untreated) and three treated groups which were fed basal diet had 10% of control beef patties, 2.5% husk tomato beef patties, and 5% HTB groups (CBP, 2.5 HTB, and 5% HTB groups). The obtained results revealed that HT powder is rich in carbohydrates, protein, and fat. The addition of 5% husk tomatoes to burgers decreased the contents of fat and ash and increased fiber and carbohydrates. The addition of 2.5 or 5% husk tomatoes to beef patties gave high scores sensory evaluation. The addition of HT to beef patties reduced lipid oxidation compared to CBP at zero time and after a week of storage. It is concluded that the addition of husk tomatoes increases the quality of the beef burger and has high efficiency in retarding lipid oxidation in the burger. 5% HTB is a functional meat product and could improve the nutritional values and treat iron deficiency anaemia in rats.
Guided mode resonances for angular and spectral filtering

The development of devices based on compact waveguides is a rapidly evolving field. A unique variation of such devices is the Fano-like resonance dielectric spectral and spatial filtre, made from a dielectric conformal thin film on a surface relief grating. It can be used in a normal (or oblique) angle-of-incidence configuration. This device facilitates directional selectivity, which is useful for transverse-mode cleaning in short optical cavities. It can also be enhanced by using leaky-mode effects to produce even sharper spectral features. However, a perfect spatial filtre should be as invariant as possible in the spectral and enhanced angular domains. Here, we solved the inverse design problem to produce such an effect. Numerically, we tuned the surface profile of the substrate grating, assuming a conformal layer on top. This resulted in trapezoidal relief patterns followed by narrow flat-top angular features. The combination of leaky mode effect and enhanced device topology will enable efficient and useful devices with a bandwidth of 50 nm and even more in the future.
The influence of Simvastatin carried by Chitosan nanoparticle on bone regeneration using Masson’s Trichrome histochemical stain

Background: Due to the complicated and time-consuming physiological procedure of bone healing, certain graft materials have been frequently used to enhance the reconstruction of the normal bone architecture. However, owing to the limitations of these graft materials, some pharmaceutical alternatives are considered instead. Chitosan is a biopolymer with many distinguishing characteristics that make it one of the best materials to be used as a drug delivery system for simvastatin. Simvastatin is a cholesterol lowering drug, and an influencer in bone formation process, because it stimulates osteoblasts differentiation, bone morphogenic protein 2, and vascular endothelial growth factor. Objectives: histological, histochemical and histomorphometrical analyses were carried out to evaluate the effect of local application of chitosan simvastatin nanoparticles (ChSimN) on bone healing. Materials and Methods: New Zealand rabbits (n=14) were used in this study. Two defects were made: one on the right side (the experimental side) that received ChSimN and the other one on the left side (the control side), which left to heal spontaneously. Seven rabbits were sacrificed after 2 weeks of the experiments, while the others after 4 weeks. Bone samples were taken for histological and histomorphometric study after the sacrifice. Results: The histological study, using both H&E and Masson’s Trichrome stain, revealed that the ChSimN group recorded an increased amount of bone formation at both time points. Histomorphometrical analysis recorded a significant increment in bone marrow and trabecular areas in the ChSimN group. Conclusion: ChSimN had a pronounced effect on bone formation.
Longitudinal variations of thermospheric composition at the solstices

O/N2, measured by the Global Ultraviolet Imager on board the Thermosphere Ionosphere Mesosphere Energetics Dynamics satellite, has large longitudinal variations at the solstices, which are simulated well in upper atmosphere general circulation models. These longitudinal variations are caused by the displacement of the Earth's magnetic poles from the geographic ones. The location of a magnetic pole affects the latitude at which the winds, driven by heating in summer, converge in the subauroral region of the winter hemisphere. In the magnetic pole's longitude sector, this convergence occurs at relatively low latitudes, which results in the maximum values of O/N2 also occurring at relatively low latitudes. These latitudes have a relatively small solar zenith angle, contributing to a strong winter anomaly. In the zonally opposite longitude sector, maximum values of O/N2 occur at relatively high latitudes because the summer‐to‐winter wind convergence also occurs at relatively high latitudes. These high latitudes have a relatively large solar zenith angle, so ionization is weak, contributing to a weak winter anomaly. Therefore, the displacement between the magnetic and geographic poles not only results in a strong longitudinal variation of O/N2 but also results in a strong longitudinal variation of the ionosphere winter anomaly.
Abundance, zonation and ecological indices of a coleopteran community from a sandy beach-dune ecosystem of the southern Adriatic coast, Italy

Les Coleopteres de l'ecosysteme plage-dune de l'Isola Varano (mer Adriatique, Gargano, Apulie) ont ete etudies de facon bimestrielle au cours de l'annee 2002. Ils ont ete echantillonnes le long de deux transects, du niveau des laisses (niveau de maree haute) jusqu'au premier cordon dunaire, par un systeme standard de pieges (animaux actifs a la surface) et de tamis (animaux enfouis dans le sable). Les variables du milieu telles que profil de la plage, exposition, orientation, longueur, largeur, pente, diametre moyen des grains et hauteur de la dune, ont ete aussi enregistrees. Les variations spatiales et temporelles des especes de Coleopteres les plus abondantes ont ete evaluees. De meme, une analyse quantitative et qualitative a ete realisee par les coefficients ecologiques suivants: frequence, abondance relative, richesse specifique, diversite a et β, indices d'equitabilite et de dominance. Le resultat de l'analyse montre que la communaute des Coleopteres de l'Isola Varano suit, tant sur le plan spatial que temporel, la tendance generale observee en d'autres points de la Mediterranee malgre les faibles valeurs de diversite enregistrees. La presence de certaines especes bioindicatrices indique un etat relativement bon de la qualite de la plage alors que la faible diversite de la faune dunaire temoigne de conditions de stress dues a la presence d'une pinede implantee dans la zone de l'arriere-dune.
